Two-Dimensional Simulation of Tunneling Using Quantum Lattice-Gas Automata

摘要

We present two-dimensional (2D) simulation of quantum tunneling across the potential barrier with surface roughness. The impact of the 2D simulation on the transmission coefficient is investigated by comparing the results with 1D simulations. It is also shown that the transmission coefficient depends on the parallel momentum of the incident particle due to the scattering by the surface roughness.
