Transfer Matrix Approach to One-Dimensional Electron Transport in Graphene Sheets with Piecewise Constant Potentials

We studied one-dimensional electron transport in a system composed of two monolayer graphene sheets with an optional arrangement of different constant rectangular electrostatic potential barriers between them. We derived a generalized transfer matrix for the electron which passes through this system. Finally, we examined our model by applying it on a well known rectangular shape constant potential barrier and we obtained the same result from our method similar to the others.
