▎ 摘  要

The Goos-Hanchen-like (GHL) shift of Dirac fermions passing through a potential barrier for an anisotropic honeycomb lattice is studied. The analytical solution of the GHL shift and numerical results of the lateral shifts for three values of the merging parameter (delta) are presented. Then, the effects of the incidence angle and delta on the lateral shifts of anisotropic Dirac electrons are considered. Moreover, we investigate the influence of the uniaxial strain on a critical angle and see that it changes as a function of energy. We also demonstrate that by changing some parameters, more specifically merging parameter, one can obtain the different shifts for graphene under strong uniaxial strain.
