In this paper we use a Multi-Subband-Monte-Carlo model to study the transport in nMOSFETs featuring strained silicon channels. It is shown that state-of-the-art modeling of the mobility in n-type inversion layers cannot reproduce the mobility enhancements measured in Si devices with either uniaxial or biaxial strain. Possible reasons for this limitation are analyzed in detail.

Abstract
In this paper we use a Multi-Subband-Monte-Carlo model to study the transport in nMOSFETs featuring strained silicon channels. It is shown that state-of-the-art modeling of the mobility in n-type inversion layers cannot reproduce the mobility enhancements measured in Si devices with either uniaxial or biaxial strain. Possible reasons for this limitation are analyzed in detail.File in questo prodotto:
