Abstract :
In this paper, we investigate the terahertz plasma oscillations in nano-scaled double-gate n-type Silicon MOSFET with 2D ensemble Monte Carlo simulation method. The effects of the drain-to-source biases, gate-to-source biases and doping levels in the source/drain regions of the devices on the terahertz plasma oscillations are considered. The relation between terahertz plasma oscillations and the channel scaling in double-gate MOSFET is also discussed. The oscillation frequency peak value as a function of doping levels exhibits a good agreement with the predictions of 2D plasma frequency.
