Electronic Properties of Semiconductor Interfaces (Springer Series in Surface Sciences, #43)
by Winfried Moench
Using the continuum of interface-induced gap states (IFIGS) as a unifying theme, Moench explains the band-structure lineup at all types of semiconductor interfaces. These intrinsic IFIGS are the wave-function tails of electron states, which overlap a semiconductor band-gap exactly at the interface, so they originate from the quantum-mechanical tunnel effect. He shows that a more chemical view relates the IFIGS to the partial ionic character of the covalent interface-bonds and that the charge tra...
