Никонов Э.Г., Назмитдинов Р.Г., Глуховцев П.И. Квазидвумерные системы играют важную роль при создании различных устройств для нужд наноэлектроники. Очевидно, что функциональная эффективность таких систем зависит от их структуры, которая может изменяться при фазовых переходах под действием внешних условий (например, температуры). До настоящего времени основное внимание было сосредоточено на поиске сигналов фазовых переходов …

E. G. Nikonov, R. G. Nazmitdinov and P. I. Glukhovtsev Quasi-two-dimensional systems play an important role in the manufacture of various devices for the needs of nanoelectronics.
