Detailed description of the invention
The storage device that the present embodiment provides, utilize the spread geometry of multiple former molecular atomic unit group Atom, represent the data bit (bit) when data store, wherein the shape of atomic unit group can move the mode of atom by atom-probe and changes, atomic unit group can be changed under atom-probe effect between two shapes, and a shape can represent data bit 0, and a shape can represent data bit 1, therefore, an atomic unit group can be used to represent data bit. For ease of the understanding to embodiment of the present invention technical scheme, atom-probe and atom storage medium will be illustrated below.
Along with people's research to material technology and atom technology, the existing technology that atom is operated, namely atom-probe technology is applied in the application technology of some atoms manipulation.
Wherein, atom-probe technology is a kind of technology that material surface carries out atom probe and operation, there is atom level high-space resolution ability, can be used for processing ultra-fine grain structure, it mainly can realize Measurement atom imaging and operation atom to ad-hoc location, wherein Measurement atom imaging just may identify which the spread geometry of atom, and operate atom and just can realize the movement of atom to ad-hoc location. At present, atom-probe technology has been widely used in the technology such as STM, wherein, utilizes atom-probe to may identify which the shape on sample surface in STM, and atom can be carried out position and move, and is described as follows.
When STM carries out atomic arrangement shape recognition, the card distance on atom-probe and sample surface is < during 1nm, surface atom is scanned by the probe tip controlled in atom-probe by piezoceramic material, thus atomic arrangement situation can be analyzed, thus atomic arrangement shape can be identified. And utilize STM to carry out atom site when moving, the active force that available atom-probe exists with sample surface, regulate position and the bias of needle point, by changing the size and Orientation of this active force, just when probe moves up, the atom on sample surface can be mentioned, again it is moved to suitable position to put down, or, it is possible to towing atom passes by surface to desired position. The specific works process of STM Atom probe no longer describes in detail at this, in detail can referring to the work process of existing STM, the present embodiment adopts atom-probe that atomic arrangement shape is identified, and atom site is moved has the work process identical with STM.
In prior art, have now been developed the material that atom is stable, for instance Wisconsin, USA university develops the silicon memory material of atom level, after silicon materials surface allows gold element distil, the accurate atomic orbital for atomic arrangement can be formed. At present, also utilizing atom-probe, from the silicon atom of marshalling, silicon atom is extracted at interval out, and to represent the data bit 0 when data store, remaining silicon atom is representative data position 1 then. But this utilize atom with or without the method representing data bit, very easily cause data storage errors because atom dislocation. For this, the embodiment of the present invention provides a kind of available atomic arrangement shape to represent the technical scheme of data bit, while utilizing atom to store as data, can improve the safety and reliability of data storage.
The structural representation of the storage device that Figure 1A provides for the embodiment of the present invention one; Figure 1B is the enlarged diagram that in Figure 1A, in annular region A, 8 atomic unit groups of continuous print arrange.As shown in FIG. 1A and 1B, the present embodiment storage device can be used for storing data, including storage medium 10, this storage medium 10 has multiple atomic unit group 11 by default aligned transfer, and each atomic unit group 11 forms by multiple atoms; The spread geometry of atomic unit group 11 Atom can change, and has first order shape and second order shape, and wherein, first order shape is used for representing that data bit 1, second order shape are used for representing data bit 0. In the present embodiment, storage medium 10 is disc-shape, and atomic unit group 11 is evenly arranged on the storage medium of this disc-shape, in multiple annular regions concentric with disk. Wherein, Figure 1A is diagrammatically only by out the region that an annular region A, wherein said annular region A are arrangement atomic unit groups; Figure 1B is diagrammatically only by out the arrangement schematic diagram of 8 atomic unit groups in A annular region.
In the present embodiment, the number of each atomic unit group 11 Atom on storage medium can be 2 or more than 2, preferably, as shown in Figure 1B, in the present embodiment, the number of each atomic unit group 11 Atom is set as 6, so, the first order shape that the arrangement of atomic unit group 11 Atom is formed can be just the rectangular shape that 6 atomic arrangement are formed, second order shape can be just the triangular shaped of 6 atomic arrangement formation, the rectangular shape A1 that 6 atoms as shown in Figure 1B are formed, and the triangular shaped A2 that 6 atoms are formed. So, above-mentioned atom-probe just can pass through one in mobile 6 atoms, it is possible to changes the shape of atomic unit group 11, it is possible to be converted to rectangle by triangle; Simultaneously, above-mentioned atom-probe can pass through to detect the spread geometry of 6 atoms in atomic unit group, determine that the data bit that atomic unit group currently represents is 0 or 1, wherein, atomic unit group Atom spread geometry represents when being rectangle that current atomic unit group represents data bit 1, and atomic unit group Atom spread geometry represents when being triangle that current atomic unit group represents that data bit is 0. So, by identifying that the shape of atomic unit group just may identify which the data bit that atomic unit group represents, thus can pass through to identify the read operation that atomic unit group Atom spread geometry realizes data; Position by mobile atomic unit group Atom, it is possible to change the shape of atomic unit group, thus by identifying the shape of atomic unit group and can be modified the shape of atomic unit group, it is possible to realize the write operation of data.
