Arithmetic logic unit design for silicon nanowire field-effect transistors logic

As dimensions of conventional planar metal-oxide-semiconductor field effect transistor (MOSFET) are reduced, it cause a lot challenging issue such as short-channel effects (SCEs), scaling of gate oxide thickness and increase power consumption. Multigate such as double gate, tri-gate, surrounding gat...
