Electron- and hole-mobility enhancements in biaxially strained metal–oxide–semiconductor transistors are still a matter for active investigation, and this brief presents a critical examination of a recently proposed interpretation of the experimental data, according to which the strain significantly modifies not only the root-mean-square value but also the correlation length of the surface-roughness spectrum.We present a systematic comparison between comprehensive numerical simulations and experiments, which supports such an interpretation.

Abstract
Electron- and hole-mobility enhancements in biaxially strained metal–oxide–semiconductor transistors are still a matter for active investigation, and this brief presents a critical examination of a recently proposed interpretation of the experimental data, according to which the strain significantly modifies not only the root-mean-square value but also the correlation length of the surface-roughness spectrum.We present a systematic comparison between comprehensive numerical simulations and experiments, which supports such an interpretation.File in questo prodotto:
