Abstract :
Nanoscale Shielded channel transistors are investigated by solving the two-dimensional Poisson equation self-consistently with ballistic quantum transport equations for first time. We present self-consistent solutions of ultrathin body device structures to investigate the effect of electrically shielded channel region which impose charge controlling in the channel region on the characteristics of nanoscale DG-MOSFET. The simulation method is based on nonequlibrium Green´s function (NEGF). Starting from a basic structure with a gate length of 10 nm, the effect of gate length variation on the performance of the device has been investigated.
