Simulation studies on electrical characteristics of silicon nanowire feedback field-effect transistors with interface trap charges

Abstract In this study, we examine the electrical characteristics of silicon nanowire feedback field-effect transistors (FBFETs) with interface trap charges between the channel and gate oxide. The band diagram, I–V characteristics, memory window, and operation were analyzed using a commercial techno...
