Electron transport properties in SiC quantized inversion layers have been studied bymeans of a Monte Carlo procedure. It has been observed that the contribution of polaropticalphonon scattering produces a significant influence of the effective-electric fieldon the high longitudinal field transport regime, this being the main difference of SiCwith respect to standard Si inversion layers. The energy- and momentum-relaxationtimes have been calculated and the results suggest that electron velocity overshooteffects are less important than in Si MOSFETs. The electron mobility is not verydifferent from their silicon counterparts, but the saturation velocity is higher
