Popis: We investigate the electronic transport properties of a finite-size silicene bilayer barrier. We got the boundary conditions at the interface of monolayer and bilayer silicene using the tight-binding model. By matching the wavefunctions, we got the transmission probability as a function of incident angle for several lengths of bilayer barrier and incident energys. We found that a clear resonant tunneling appears because of evanescent modes in bilayer silicene. We also calculate the conductance in a overlap configuration which displays an oscillatory behavior as increase of either incident energy or length of bilayer barrier.
