Definitions
- Nitrides of group III elements InN, GaN, AlN
- their alloys and their heterostructures have very interesting properties for applications in electronics and optoelectronics.
- the set (AI 1 GaJn) -N makes it possible to describe the entire electromagnetic spectrum of interest for communication and information processing technologies, from the near infra-red to the ultraviolet-type C. As a result, their optoelectronic applications are larger than those of other families of semiconductor material.
- the forbidden band of the indium nitride InN corresponds to a wavelength of approximately 1.8 ⁇ m, that of the aluminum nitride AIN at 200 nm and that of the gallium nitride GaN at 350 nm. Since it is known to produce alloys whose composition varies continuously between the three binaries In, Al and Ga, where it is also known to assemble these binaries into heterostructures with wells and quantum dots, then we can cover from these materials the telecommunication bands to 1, 3 microns and 1, 5 microns, or make visible light emitting devices (light-emitting diodes, lasers) or realize photodetectors inaveuglables the sun.
- nitrides are also chemically inert, and therefore do not pose the same dangers as arsenic, phosphorus or antimony in terms of pollution. This family of materials thus respects the environmental constraints prescribed during the signing of the Kyoto protocol.
- Indium nitride is among the nitrides of element III the most difficult to synthesize with a crystalline quality compatible with the intended applications.
- the incorporation of indium into the crystalline matrix of the nitride can not effectively be done without generating strong constraints and numerous dislocations of networks with deleterious consequences for any electronic component. It is therefore not possible today to obtain an InN film of sufficient quality, especially in terms of crystallinity, for the intended applications.
- An object of the invention is to allow the synthesis of group III nitride-based films or nano-objects having a crystalline quality superior to that which exists in the state of the art, in order to be able to fully exploit the properties of these materials in an industrial way.
- the invention proposes a method for the growth of element III nitride, in which the growth is carried out on a substrate made of a material able to maintain the same crystalline structure since the nitride growth temperature.
- the substrate being an alloy of the type MVO 4 , where M denotes a transition metal or a group III element, and where V denotes N, P, As or Sb, or an alloy of the type (Si-IV) O 2 , where IV denotes a group IV element other than silicon.
- indium nitride InN is deposited on an AIPO 4 substrate;
- gallium nitride GaN is deposited on a GaPO 4 substrate;
- an alloy consisting of GaN and GaInN is deposited on a GaPO 4 substrate; the growth of the element III nitride on the substrate is carried out by epitaxy; and
- the growth of the element III nitride on the substrate is carried out by spraying.
- the invention relates to a structure for an application in electronics, optics or optoelectronics comprising a nitride element III deposited on a substrate of a material capable of maintaining the same crystalline structure since the temperature element III nitride growth to ambient temperature, the substrate being an MVO 4 alloy, where M is a transition metal or group III element, and V is N, P, As or Sb , or an alloy of the (Si-IV) O 2 type , where IV denotes a Group IV element other than silicon.
- the invention also relates to the components comprising a structure as described above.
- FIG. 1 is an atomic force microscopy image showing the morphology of an AIPO 4 substrate
- FIG. 2 represents an X-ray diffraction spectrum indicating the crystallinity of the AIPO 4 substrate;
- FIG. 3 is an atomic force microscopy image showing the morphology of indium nitride deposited on an AIPO 4 substrate in accordance with the invention
- FIG. 4 represents an X-ray diffraction spectrum indicating the crystallinity of the indium nitride deposited on an AIPO 4 substrate in accordance with the invention
- FIG. 5 represents a fluorescence spectrum indicating the emission of light of the indium nitride deposited on an AIPO 4 substrate in accordance with the invention.
- the invention relates to a method for the growth of element III nitride on a substrate, in which the growth is carried out on a substrate made of a material able to maintain the same crystalline structure since the growth temperature of the nitride of element III to room temperature.
- nitrides of group III elements of the Mendeleev table are in particular aluminum nitride, gallium nitride and indium nitride, as well as mixed nitrides.
- Indium nitride is particularly targeted, but the invention is in no way limited to this particular nitride, but instead is intended to extend to other element III nitrides and their heterostructures.
- the term “film” means a continuous layer, preferably a thin layer, of a thickness generally between 1 atomic monolayer and 10 microns.
- the term “nano-object” means an individual structure having at least one nanometric dimension, between 1 and 50 nm.
- the element III nitride which is grown by the method according to the first aspect of the invention may in particular be a film or a nano-object such as a quantum dot.
- the invention thus relates as well to the nitride films of elements III as their heterostructures, wells and quantum dots as well as the objects generally used in photonics: microcavities, photonic membranes textured technologically or during selectively induced growth, photonic crystals produced by three-dimensional cross-growth ("wood stack stacking").
- the substrate used in the context of the invention for the growth of element III nitride is preferably a compound of the family of quartz and berlinite.
- These materials composed of the ordered phase type MVO 4 (where M designates a transition metal or a group III element, and where V denotes N, P, As or Sb) or alloys of the (Si-IV) O 2 type (where IV denotes a group IV element other than silicon), have the advantage of having a higher alpha-beta or alpha-cristobalite phase structure transition temperature than the synthesis temperature of the element III nitride.
- the growth of the element III nitride can then be carried out on a substrate whose crystalline nature is preserved after growth of said nitride when the system is brought back to ambient temperature (operating temperature of the components).
- quartz SiO 2 has a relatively low alpha-beta structural phase transition temperature (573 ° C.). Depending on the type of element III nitride considered, quartz SiO 2 is not likely to maintain the same crystalline structure from the growth temperature of the nitride to room temperature.
- the growth temperature of the element III nitride on a substrate varies according to the nitride.
- the indium nitride InN is thus always deposited at a temperature below its decomposition temperature 600 ° C.
- the GaN gallium nitride is generally deposited at a temperature of about 800 ° C.
- a GaPO 4 substrate appears to be well suited for depositing a GaN film and GaInN-GaN heterostructures which are blue light-emitting diodes, blue compact lasers and transistors.
- an AIPO 4 substrate is suitable for the growth of indium nitride.
- the growth of the element III nitride is carried out by epitaxy.
- the growth can be carried out by molecular beam epitaxy ("MBE"), by epitaxy by metal vapor phase organometallic deposition (“MOVPE”). of the English acronym “MetalOrganic Vapor Phase Epitaxy”), by epitaxy HWE (the acronym for "Hot Wall Epitaxy”), by epitaxy MEE (the English acronym "Migration Enhanced Epitaxy”) .
- the growth of the element III nitride is carried out by sputtering.
- the source materials are evaporated, either thermally or by electron bombardment, and will condense on the surface of the substrate, at low temperature. Due to the moderate temperature of the substrate, the crystalline quality of the deposited material is lower, most of the time it is polycrystalline.
- the surface of the substrate Prior to the growth of element III nitride, the surface of the substrate may be subjected to a surface preparation step to improve its physical properties for growth.
- a surface preparation step to improve its physical properties for growth.
- One or more of the following techniques can be implemented: heat treatment, polishing, chemical etching, or other techniques known to those skilled in the art.
- the invention relates to a structure for an application in electronics, optics or optoelectronics comprising one or more films or one or more nitride nano-objects of element III, carried by a substrate of a material capable of maintaining the same crystalline structure from the growth temperature of the element nitride III to ambient temperature, in particular a substrate of the MVO 4 or (Si-IV) O type 2 as previously described.
- the invention relates to a component for electronics, optics or optoelectronics comprising a structure according to the second aspect of the invention.
- indium nitride is the most difficult material to synthesize materials of the Ml-N family.
- Indium nitride is deposited by epitaxial growth, MOCVD, on an AIPO 4 substrate.
- the growth parameters used are typically a growth temperature of 500 ° C., a pressure in the reactor of 200 mbar and a V / III ratio of about 20,000.
- the value of the molar ratio V / III is strongly correlated with the type of growth reactor used. This molar ratio affects in particular the stoichiometry of the processed material; a molar ratio V / III too low will thus result in films containing indium metal.
- the pressure in the reactor can be chosen between 20 and 1 000 mbar.
- the growth temperature is limited to the range 250 ° C. to 650 ° C., the dissociation temperature of the indium nitride being effectively around 700 ° C.
- FIG. 1 shows the morphology of the AIPO 4 substrate (as observed under an atomic force microscope).
- Figure 2 illustrates the crystallinity of the AIPO 4 substrate (observed by X-ray spectrography, the X axis representing the angular deviation of the incident X-ray beam and the Y axis showing the electromagnetic intensity collected. ).
- FIG. 3 shows the morphology of the indium nitride deposited on the AIPO 4 substrate (observed under an atomic force microscope), in FIG. 4 the crystallinity of this indium nitride (observed by X-ray spectrography). ) and in Figure 5 the fluorescence spectrum of this indium nitride (obtained at 77K).
