TSU scientists have become the first in Russia to begin to grow semiconductors from organic molecules in the gas phase. To do this, they use an installation that allows the creation of super-thin films, whose thickness is 5,000 times smaller than a human hair. The self-assembly of molecules leads to the emergence of semiconductor structures that provide increased speed of devices with minimal energy costs. Based on these semiconductors, devices of molecular nanoelectronics can be developed that will bring humanity to a new technological level.
Earlier, it was impossible because of the lack of equipment. This year, TSU SPhTI was the first in Russia to get an industrial installation for growing semiconductors from molecules of organic compounds. One company from Israel has arranged it as an order of the University.
Devices on semiconductors created by the method of molecular epitaxy will differ fundamentally from what has been done in the usual way. Their energy consumption will decrease significantly and the speed will increase at times.
The technology of growing organic semiconductors created at TSU will eliminate one of the main problems of molecular electronics and nanoelectronics. It consists in the fact that all devices made on the basis of organic conductive materials decompose under the influence of time, loads, and temperature. The new technology makes it possible to form very strong bonds between molecules, which will significantly prolong the life of the technical equipment.
It will have much more functionality, but it will cost much less. To produce organic semiconductors, very high temperatures are not needed, 300-400 C° is sufficient, which is at least half that of the working temperature for inorganic semiconductors.
