#graphite alkene

The researchers of Britain Manchester university have succeeded in developing the transistor-resistor logic minimum in size, its thickness is an atom, the section is 10 atoms.

This great progress has already been issued on the latest Science, and broken the graphite alkene transistor-resistor logic world record of sectional 100nm that this group created last year.

Graphite alkene was connected in an intricate way by carbon atom, even if there is the thickness of a atomic layer that can also keep a lot of characteristics - -Among them the most important thing is the conductivity. Crystal quality and electricity characteristic of this material are surprisingly high, and researchers claim that there is several potential application to condense attitude physics and electronic device field.

The scientist of U.S.A. Maryland university showed last month, it was only one atom thick pure carbon structure that they had already signified single-storeyed graphite alkene out. Different from most semiconductor materials, they find the characteristic of graphite alkene does not vary with temperature.

The group of Manchester adopts the standard semi-conductive manufacturing technology and makes transistor-resistor logic out. Begin with a small graphite alkene lamella, adopt the electron beam exposure and carve the channel out on the material. On a quantum dot with little small circle cage of station keeping of middle part known as the central island. The voltage can change the conductivity of these quantum dots, can store the logic attitude like standard field effect transistor in this way.

Under the leading of physics and astronomical Dr. Kostya Novoselov of institute and Andre Geim professor of the university of Manchester, the latest research develops to reveal, the transistor-resistor logic that can be made of graphite alkene makes up the very small circuit, the size of the transistor-resistor logic is not much older than single atom.

But Dr. Novoselov points out cautiously, can't produce large-scale graphite alkene yet at present. They can only produce graphite alkene crystal of about 100 microns of section, this is really too small to should use in industrying.

" perhaps can solve this problem over the next several years, " He says so.

After the size that the master shortcoming is the material is smaller than 10 nanometers, its stability is very bad. Under this kind of space dimension, all semiconductors - -Including silicon - -Will all oxidize, decompose, it is moved and not controlled along the surface, just the same as the water droplet drop on hot plate.

Four years ago, Geim and his colleagues in Manchester became the first group that studied graphite alkene, this material is a material of the first kind of monoatomic thickness, can regard as level of a layer of atoms collected the graphite structure. Graphite alkene had already become one of the research directions that semi-conductive material science is hottest hereafter.

"Before this, in order to obtain the new circuit structure, researchers adopt the macromolecule to prepare single transistor-resistor logic. Add some chemical methods into computer project " ,Novoselov appraises like this. "it and make up now last kinds of materials the same molecule of transistor-resistor logic computer framework when and it is final ( Graphite alkene) Make, can consider their direct connection. And it was the manufacturing approach the same as semi-conductive industry at present that adopted. "

Geim adds: "It is early to make the promise of the supercomputer of graphite alkene. We are not very high either when making such a small transistor-resistor logic success rate. Unfortunately, have not really cut the technology of the material with the nanometer precision yet at present. But this is a challenge that the electronic device needs facing of era of silicon after all. We have a kind of material that can meet such requirement now at least. "

"These transistor-resistor logics can work, and can work in the air, under the room temperature condition - -The environment that the electronic device can be used at present that that is to say, " Geim introduces so. He still adds the characteristic of graphite alkene " Surmount " A order of magnitude of silicon, are similar to other preferably material characteristics, and adopt graphite alkene craft and silicon craft of producing circuit to be very compatible.

"We adopt the step the same as silicon industry to make transistor-resistor logic at present. So once we have enough large graphite alkene wafer, all right that that adopts the same process sequence directly. "
