In this paper, we have studied the effect of different parameters on carrier mobility in NWFET devices. Their characteristics have been investigated using the non-equilibrium Green function (NEGF) method. Our work involves the carrier mobility µ as a function of VDS taken from 0.1 V to 1 V for various gate lengths, namely: 10, 20, 30, 40, and 50 nm. Then, the variation of µ as a function of the width of the nanowire varied from 2 to 6 nm. After that, we have simulated µ as a function of the oxide thickness for the values: 2, 4, and 6 nm. Moreover, the mobility has been considered as dependent on the composition of high- materials, namely: SiO₂, HfO₂, ZrO₂. Our results clearly show that device characteristics can be improved by selecting geometrical and physical parameters.
