Tóm tắt
Though, high dielectric constant material is a possible near future candidate to suppress gate current densities of MOSFETs, the barrier height generally decreases with increasing dielectric constant. In this paper, the injection current through gate stacks has been calculated while taking into account the electron temperature using the W.K.B. method to understand the impact of the injection current from the drain edge.
