Siberian scientists have learned how to make diamond film thickness of 30 nanometers — an order of magnitude thinner than they produce in Europe and the U.S., said the head of the laboratory of the Institute of Semiconductor Physics (ISP) Rzhanova behalf of the Siberian Branch of the Russian Academy of Sciences Vladimir Popov.
The scientist explained that the smaller the thickness of the chip material, the less there is of parasitic effects and noise, lower power consumption, so the film of nanometer thickness — an ideal base for chips. For example, a silicon film thickness of one nanometer, developed in the Institute of Semiconductor Physics, use the organization of Rosatom and Russian Federal Space Agency for the development of devices, radiation-resistant electronics institutes of RAS and RAMS use them in nanoelectronic devices and biosensors. The agency's interlocutor said that now the diamond films with a thickness of 300 nm is obtained in several laboratories around the world, but all their undoubted advantages are crossed so-called residual defects, which are formed by separating the film from the crystal.
"We found a way to avoid the appearance of defects at all stages of the process and keep the original structure of the synthetic crystal is grown by our colleagues from the Institute of Geology and Mineralogy, Russian Academy of Sciences", — Popov said.
Using quantum optical effects in diamond chips on the orders will increase the amount of computation computers. Furthermore, diamond chips can operate at temperatures up to plus 800 degrees Celsius, in particular, would allow direct control devices to create and control of jet engines and others. The scientist noted that when there will be technology to make chips of the hardest mineral on earth, a diamond can push the market silicon microelectronics. But you need to grow a crystal with the desired properties, peeled learn from it the finest film and embed it in the crystal structure of other chemical elements (doped) to boost its low electrical conductivity.
