Abstract

The thermoelectric effect of the system is theoretically investigated, by coupling Majorana zero mode to the T-typed double-quantum-dot-structure in different ways. It is found that when a single Majorana zero mode is coupled to one of the quantum dots (QDs), the thermoelectric efficiency is suppressed due to the leakage of Majorana zero modes into the QDs. When the Majorana zero mode is coupled to QD2, the suppression of the thermoelectric efficiency is more serious than that of QD1. Furthermore, when two Majorana zero modes are introduced simultaneously, suppression of the thermoelectric effect still takes place. We believe that such results can be candidates for the detection of Majorana bound states and help us understand the role of Majorana zero mode in thermoelectricity.
