Abstract :
The recently reported larger mobility degradation at higher transverse electric fields and lower temperatures is explained based on the physics of electron population and scattering mechanisms of quantized subbands at (100) Si surfaces. The simple empirical mobility model proposed by T.-C. Ong et al. (ibid., vol.34, no.10, p.2129-35, 1987) is also discussed
