Description
The problem on the electrons capture by the crystal twin boundary is solved. The energy of the basic and the first excited state of the large radius polaron is calculated through the variation method within the strong bond limit. The results of the accomplished calculations show, that the polaron energy at the boundary is by three times less than that one of the voluminous polaron and only in the excited state it is not suitable for the electron to get localized near the boundary
Abstract (Russian)
Решается задача о захвате электрона двойниковой границей кристалла. Прямым вариационным методом вычислена энергия основного и первого возбужденного состояния полярона большого радиуса в пределе сильной связи. Установлено из результатов приведенных расчетов, что энергия полярона на границе почти в 3 раза меньше, чем объемного полярона, и только в возбужденном состоянии электрону невыгодно локализоваться вблизи границыAdditional details
