Definitions
- the invention relates to a method for producing a metal electrode on the surface of a hydrophobic material.
- Hydrophobic materials are known which may have interesting physical characteristics for the field of electronics. Graphene, for example, has photonic characteristics that could greatly contribute to the field of optoelectronics. However, it is difficult to produce a quality electronic device from a hydrophobic material. It is particularly complex to deposit an electrode on a pure hydrophobic material.
- a method of producing a metal electrode comprising the step of approaching a hydrophobic material with an end of a capillary, containing a fluid which comprises metal particles in solution.
- the deposition of a drop of fluid on the surface of the material is then caused by the Electrospray Ionization (ESI) technique: the end of the capillary and the surface of the material are subjected to an electric field very important by means of an electrode in contact with the end of the capillary and an electrode in contact with the surface of the hydrophobic material so that an electric current is established between the electrodes.
- the metal particles contained in the fluid of the capillary then migrate under the effect of the electric field towards the electrode in contact with the surface of the material.
- the invention relates to a method of producing a metal electrode on the surface of a hydrophobic material to overcome the aforementioned drawbacks.
- a method for producing a metal electrode on the surface of a hydrophobic material comprising the steps of:
- the laser radiation thus creates electrostatic charges by local ionization of the hydrophobic material. Electrostatic forces between charged particles contained in the material and charged particles contained in the metal particles of the fluid are thus exerted. These electrostatic forces create an electric field between the end of the capillary and the surface of the material. Under the action of the electric field, free charges contained in the fluid at the end of the capillary move this which causes a macroscopic movement of the fluid. Such a phenomenon is called the phenomenon of electroosmosis. Thus, the movement of the fluid causes the formation and flow of drops at the end of the capillary. The laser radiation then makes it possible to form the metal electrode once the drop has been deposited on the surface of the material.
- the end of the capillary is thus in no way subjected to a high voltage so that the invention prevents local evaporation of the fluid at the end of the capillary.
- FIG. 1 is a schematic representation of an operating device implementing the method according to the invention
- FIG. 2 is a schematic representation of the various steps (a, b, c, d) of the method according to the invention.
- the method according to the invention is intended to be implemented in an operating device comprising a computer 1 making it possible to control an inverted microscope 2 to which a laser 3 is connected, the inverted microscope 2 and the laser 3 forming a fixed set.
- the computer 1 also controls a first manipulator arm 4 that can in operation move a capillary 5 relative to the microscope 2 and the laser 3 along two axes X, Y of translation in a plane and a translation axis Z perpendicular to this plane.
- the computer 1 also controls a manipulator (not shown here) that can in service move a sample 6, with respect to the microscope 2 and the laser 3 along the two axes X, Y of translation in the plane and the translation axis Z perpendicular to this plane.
- the capillary 5 contains a fluid which comprises metal particles, here gold particles, dissolved in a solvent.
- Sample 6 comprises a first thin layer of a hydrophobic material 7 deposited on a suitable substrate 8. According to a preferred embodiment, the first layer
- the substrate 8 is borosilicate glass.
- the substrate 8 faces the laser 3 and the first layer 7 faces the capillary 5.
- the sample 6 is for example prepared as follows. A thick layer of the hydrophobic material is placed against a surface of the substrate 8. The substrate 8 is then raised to a high temperature which causes the substrate 8 to dissociate the oxides it contains. The substrate 8 and the thick layer 10 are then subjected to an electric field by means of an electrode in contact with the substrate 8 and an electrode in contact with the thick layer 10. The dissociation of the oxides in the substrate 8 makes the substratum
- step (b) of FIG. 2 it suffices then to eliminate most of the thick layer 10 to leave only the first thin layer 7 bonded to the substrate 8 and thus form the sample 6.
- the method of depositing a metal electrode then proceeds as follows. With reference to step (c) of FIG. 2, once the sample is in place in the device of FIG. 1, one end of the capillary 5 is approached near an area of the first layer 7.
- the laser 3 then illuminates the zone of the first layer 7 which causes a creation of electrostatic charges by local ionization of the first layer 7. Electrostatic forces are thus exerted between charged particles in the first layer 7 and charged particles contained in the particles metal of the fluid. These electrostatic forces thus create an electric field between the end of the capillary 5 and the zone of the first layer 7.
- the electric field causes, by electroosmosis, a movement of the fluid contained in the capillary 5 which in turn causes the formation and the flow of a drop 9 at the end of the capillary 5. By falling on the area of the first layer 7, the drop 9 forms a fluid deposit.
- the fluid contained in the capillary 5 is thus simply deposited on the first layer thanks to the electrostatic forces created between charged particles contained in the first layer 7 and charged particles contained in the metal particles of the fluid as well as to the electro-osmotic field created in the capillary 5.
- the area where the drop 9 is made is defined by moving the sample 6 relative to the capillary 5. Similarly, the dimensions of said deposit are controlled by bringing the sample 6 closer to or away from the capillary 5.
- the laser illuminates through the substrate 8 the zone where the drop 9 has been deposited so as to warm up locally. said area.
- the drop 9 is thus also heated which causes the progressive evaporation of the solvent contained in the drop 9, the laser 3 concentrating the gold particles in the center of the drop 9. Simultaneously, the heating of the drop 9 causes annealing of the particles.
- metal particles on the surface of the first layer 7 thus forming a metal electrode on the surface of the first layer 7.
- the radiation of the laser 3 passes through the substrate 8 to illuminate the area of the first layer 7, it will of course be possible to directly illuminate the zone of the first layer 7 without passing through the substrate by directly illuminating the free face of the hydrophobic material.
