Analysis of electron capture at oxide traps by electric field injection
Journal article, 2013

Electron injection into oxide traps of metal/high-k oxide/interlayer/silicon structures is investigated by modeling. We demonstrate the influence on flat-band voltage by the sharpness of the interlayer/silicon interface and by the properties of traps in the oxide. Since charge carrier injection in this kind of structures may take place by two different processes simultaneously, excluding one or the other in the interpretation of data may lead to considerable erroneous results in extracted values of capture cross sections.
