AltSU chemists are developing a model of improved semiconductors

The team of researchers, led by Yulia Terentyeva, Associate Professor of the Department of Physical and Inorganic Chemistry of the Institute of Chemical Physics and Technology, Candidate of Physical and Mathematical Sciences, includes students and graduate students of the institute who are engaged in the study of semiconductor systems, including those doped with 3d metals.

The project of scientists from the Institute of Chemistry and Chemical and Pharmaceutical Technologies of AltSU is aimed at creating a model of saturation of semiconductors with 3d metals.

“Our task is to determine the amount of 3d-metal that will be optimal for the appearance of new properties of semiconductors, since their deficiency will not give the desired result, and an excess of the semiconductor lattice may even collapse. The computer experiments we have already carried out have shown good results, comparable to practical experiments carried out in various scientific institutes of the country”, Yulia Terentyeva emphasized. “We identify the content of the 3d doped metal, which allows the initial semiconductor to acquire magnetic properties without losing its semiconducting properties”.

AltSU scientists are engaged in fundamental research of semiconductor compounds, the results of which can be further applied to create new elements of telephones, computers, televisions and other electronics, up to the space industry. So, for example, if an ordinary semiconductor can be used in lasers, microcircuits and various electronics, then doped with 3d metals can be used as elements of spintronics devices that also use the magnetic properties of semiconductors.

“Before, no one has conducted such theoretical studies so far, and therefore the computer modeling and quantum-mechanical calculation we perform allow us to predict the properties of the system that we are studying. And since our results are consistent with the results of field experiments, the results of our work can become the next step in the fundamental research of nanoelectromechanical systems of semiconductor multicomponent compounds based on semiconductor matrices”, concluded the head of the research group.

It is worth noting that the project "Computer modeling of nanoelectromechanical systems of semiconductor multicomponent compounds" was among the winners of the competition of intra-university grants for young scientific and pedagogical workers of Altai State University, which was held at the flagship university of Altai Krai from March to April 2020.
