Almost all semiconductor devices contain metal-semiconductor, insulator-semiconductor, insulator-metal and/or semiconductor-semiconductor interfaces; and their electronic properties determine the device characteristics. This is the first monograph that treats the electronic properties of all different types of semiconductor interfaces. Using the continuum of interface induced gap states (IFIGS) as a unifying theme, Monch 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...
