Abstract:
We theoretically investigate the effect of the Majorana fermion on the transport properties through quantum dot hybrid system. With the framework of the generalized master equation method, we analyze the current through system, differential conductance and Fano factor as a function of bias. Our results reveal that the coupling of the Majorana fermion and electrons on the quantum dot can lead to a zero-bias anomaly, while the coupling of the two Majorana fermion inhibits the zero-bias anomaly, and relevant underlying physics problems is discussed.
