摘要
In this paper, we study the charge distribution in the inversion layer of a strained Si/strained Si1-xGex dual channel pMOSFET on relaxed Si1-yGey. First, the size quantization of the two-dimensional hole gas (2 DHG) in the strained layers is discussed based on the Schrodinger equation with a complete description of the valence band structure using the k . p-method (KPSE). Second, the heterojunction valence band offsets needed for modeling in commercial TCAD device simulators are estimated for the first time from the results of the KPSE.
