▎ 摘  要

Using the transfer matrix method, the carrier tunneling properties in graphene superlattice generated by the Thue-Morse sequence and Kolakoski sequence are investigated. The positions and strength of the transmission can be modulated by the barrier structures, the incident energy and angle, the height and width of the potential. These carriers tunneling characteristic can be understood from the energy band structures in the corresponding superlattice systems and the carrier's states in well/barriers. The transmission peaks above the critical incident angle rely on the carrier's resonance in the well regions. The structural diversity can modulate the electronic and transport properties, thus expanding its applications.
