Oleg Tolbanov

Oleg Petrovich Tolbanov (born: 3 February 1947; Tomsk, USSR) is a Russian physicist, specialist in solid state physics, solid-state electronics and physical materials science. He is the author of more than 160 scientific articles in the Web of Science database (Hirsch Index - 15), including: monographs, 5 textbooks, more than 60 inventions.

Early life
On 3 February 1947, Tolbanov was born in Tomsk, USSR.

Education
Tolbanov graduated from school in 1965 and entered Tomsk Institute of Radio Electronics and Electronic Engineering.

Career
In 1966, Tolbanov was a member of the avant-garde brigade of the Tomsk student construction team participated in clearing the site for construction of the capital of oil industry, the city of Strezhevoy (Tomsk region).
 * From 1970 to 1974 Oleg P. Tolbanov worked at the Research Institute of Semiconductor Devices (Tomsk), rising from an engineer to a leading designer.
 * From 1975 to the present time Oleg P. Tolbanov works at Tomsk State University. Under his leadership, the Scientific school and Laboratory of Functional Electronics were established, in which work is carried out related to the study of patterns, development of semiconductor doping technology with impurities with deep energy levels and building of structures and devices based on it.
 * In 2016, thanks to the developed detectors, they entered the ATLAS experiment group, which is searching for super-heavy elementary particles, such as the Higgs Boson, at the European Center for Nuclear Research (CERN).

Previously unknown scientific facts were discovered: – marginal compensation of GaAs with chromium impurity, which makes it possible to achieve a specific resistance of more than 1 GΩ * cm (higher than in its own semiconductor); – corrugation of the energy bands, leading to formation of recombination barriers, allowing a more than 100-fold increase in the lifetime of charge carriers in a compensated semiconductor.

Tolbanov is the head of Laboratory of Functional Electronics at Institute of Smart Materials and Technology.

Personal life
Tolbanov is married and has two daughters, Anna and Lyudmila.
