In state of the art devices, it is well known that quantum and Coulomb effects play significant role on the device operation. In this review article we demonstrate that: (1) proper treatment of the short-range Coulomb interactions is needed, and (2) there are significant variations in device design parameters for devices fabricated on the same chip due to the presence of discrete dopant atoms at random locations within the channel. The influence of unintentional dopants is also examined in both narrow wire SOI devices and FinFETs with a three-dimensional (3D) in-house Monte Carlo-Molecular Dynamics Device Simulator.
