With the aid of the transfer matrix method, the carrier tunneling properties in a two-dimensional (2D) structure with an anisotropic linear energy
dispersion are investigated. Several factors, the barrier structure, the incident energy, and the incident angle can be applied to modify the
transmission characteristics. An impressive fact is that the anisotropic parameter and different potential directions can be used to tune the Klein
tunneling. Therefore, the features of the normal incident transmission and the controllable side resonance transmission peaks can enrich the
transport properties in a 2D system and are useful for the designing and utilization of electronic devices.
