We simulated a Single Electron Tunnel (SET) Transistor with the full inclusion of inelastic macroscopic quantum tunneling of charge (q-MQT) or co-tunneling. Numerical results of the q-MQT effect over a wide range of bias and gate voltage were achieved.Monte Carlo method was used to simulate electrons that tunnel back and forth through the two tunnel junctions of the SET transistor and co-tunnel back and forth through both junctions simultaneously.Resonances in the I-V characteristic were found. The resonant peaks decrease with increasing temperature. The origin of this resonance is the q-MQT or co-tunnel effect in contrast with the normal resonant tunneling in double barriers.

ABSTRACTWe review recent results on intrinsic frictional properties of adsorbed monolayers, composed of mobile hard-core particles undergoing continuous exchanges with a vapor phase. In terms of a dynamical master equation approach we determine the velocity of a biased impure molecule - the tracer particle (TP), constrained to move inside the adsorbed mono-layer probing its frictional properties, define the frictional forces exerted by the monolayer on the TP, as well as the particles density distribution in the monolayer.
