Analysis on channel thickness fluctuation scattering in InGaAs-OI MOSFETs

Abstract

Effects of channel-thickness-fluctuation scattering on electron mobility have been analyzed and it was found that channel-thickness-fluctuation scattering is important parameters decide mobility in ETB III-V-OI MOSFETs. Also, we have clarified that the introduction of MOS interface buffer layer is effective to enhance mobility through the increase of μfluctuation.
