▎ 摘  要

We address the problem of Dirac fermions' graphene quantum well and we focus on the low energy approximation for the Hamiltonian of the system where the former can be described by a Dirac-like Hamiltonian. Interesting relations are obtained and used to discuss the influence of the spin orbit coupling, which induces an effective mass-like term mv(F)(2), on the transport properties of Single-layer graphene quantum well. It is found that the reflection probability of incident electrons is sensitive to the effective mass-like term mv(F)(2). This can be explained by the dependence of R on the incident electrons' direction and their energies. Notably, we found that the reflection probability for massive fermions with a very small angle, i.e. the wave-vector along the transport direction is zero in the GQW, can be greatly suppressed.
