Surface States

Surface Structure—Experimental Methods

“…Determination of some surface-state characteristics can thus be achieved by measurements made on the space-charge layer as it is modified by external agents. Comprehensive reviews of this work exist (206)(207)(208)(209)(210)(211)) so that we need not go into it in depth. We shall content ourselves with a brief review of the principles underlying the methods and a discussion of some recent experiments, particularly those done on well-characterized surfaces.…”

Физический Механизм Работы Скандатных Катодов СВЧ Приборов

“…1. Таблица составлена с учетом того, что в ионных кристаллах с широкой запрещенной зоной дефекты донорного типа в объеме кристалла создают на поверхности дефекты акцепторного типа, а дефекты акцепторного типа в объеме кристалла создают на поверхности дефекты донорного типа [6]. На рис.…”

Nanocatalysis: hypothesis on the action mechanism of gold

“…These surface electron states have a discrete energy spectrum and wavefunctions that exponentially decay with increasing distance from the surface to within or away from the crystal. During more than 80 years since then, the theory of surface states has been considerably developed with regards to computational techniques and the analysis of such states in various crystals [66,67]. Due to the evolution of nanoscience, the problem of surface states has become even more relevant.…”
