外文摘要：We investigate the peak structure in the interlayer conductance of Moiré superlattices using a tunneling theory we developed previously.The theoretical results predict that,due to the resonance of two different partial waves,the double-peak structure can appear in the curve of the interlayer conductance versus twist angle.Furthermore,we study the influences of the model parameters,i.e.,the chemical potential of electrodes,the thickness of Moiré superlattice,and the strength of interface potential,on the peak structure of the interlayer conductance.In particular,the parameter dependence of the peak structure is concluded via a phase diagram,and the physical meanings of the phase diagram is formulized.Finally,the potential applications of the present work is discussed.
