Abstract :
The aim of this work is to show the dependence of the time dependent current of gate-all-around transistors on their geometries and thus to find out how to optimize their intrinsic AC behavior. The Ramo-Shockley-Pellegrini (RShP) theorem and many-particle Monte Carlo technique are used, through the recently developed BITLLES simulator which is devoted to simulate classical and quantum electronic devices, to tackle this problem. Analytical and Monte Carlo (MC) simulations show how the HF spectrum noticeably depends on the ratio between lateral (Ly, Lz) and longitudinal (Lx) dimensions of a gate-all-around transistor.
