Vadim Evgenievich Lashkarev and optoelectronics


On 7 October 2023, the scientific community celebrated the 120th anniversary of the birth of

Vadym Yevhenovych Lashkariov, a physicist, discoverer of the p-n junction, teacher, organiser of science, and

simply a smart and decent person (07.10.2003 - 01.12.1974). In our opinion, the significance and influence of

V.E. Lashkarev on the further development of physics, in particular semiconductor physics in Ukraine, has not

been sufficiently revealed, although a number of articles have been published over the past decades on the life

and scientific work of Vadym Yevhenovych. This article aims to look at the scientific work of Vadym

Yevhenovych in the light of the newly emerging field of optoelectronics. The article shows some new aspects of

the life and work of Academician of the National Academy of Sciences of Ukraine Vadym Yevhenovych

Lashkariov, which are based on documents signed by him personally. Despite the blows of fate: exile and the

Second World War, Vadym Yevhenovych retained his scientific inspiration and a far-sighted vision of the

development of a new scientific field - semiconductor physics. The directions of the V. Lashkarev scientific

school of semiconductor physics are analysed in details: studies of generation-recombination processes and

electronic transport in semiconductors and semiconductor structures; theoretical and experimental studies of

surface phenomena in semiconductors; theoretical and experimental studies of electronic transfer of two-

dimensional free charge carriers in semiconductor nanostructures; studies of electrophysical and photoelectric

effects in semiconductors and layered structures. Some examples of monographs and articles by students and

followers of the V. Lashkarev scientific school, who developed the initial scientific fields and modernised the

physics of semiconductors, are given.
