Спектр одноэлектронных состояний кристалла германия с дефектами замещения атомами 3d-элементов

Abstract

Model of a high-symmetric cluster with the closure of broken valencies by hydrogen atoms and computing scheme on the base of the density functional theory with an exchange-correlation potential of Perdew-Burke-Erzerhof in valent basis of two-exponential orbitals with usage of an effective spanning pseudopotential of a los-alamos type were applied to calculate energy spectrum of electrons in germanium, its ideal structure and its structure with local defects of substitution of germanium atoms for the 3d-element atoms. The peculiarities of the energy scheme (one-electronic states), caused by introduction the transition elements into the germanium structure were analysed.

Модель высокосимметричного кластера с замыканием разорванных валентностей атомами водорода и вычислительная схема на основе теории функционала плотности с обменно-корреляционым потенциалом Пердью – Бурке – Эрзерхофа в валентном базисе двухэкспонентных орбиталей с использованием эффективного остовного псевдопотенциала лос-аламосского типа применены к расчету энергетического спектра электронов в германии, как идеального строения, так и с локальными дефектами замещения атомов германия на атомы 3d-элементов. Проанализированы особенности энергетической схемы (одноэлектронных состояний), обусловленные введением в структуру германия атомов переходных элементов.
