The differential conductance of In/Bi2Te3 contact under cryogenic temperature is investigated. Anomalous zero/finite bias differential conductance has been observed. The dependence of the observed anomalous differential conductance on magnetic field and temperature is studied. Data analysis indicates that the anomalous differential conductance is caused by the peculiar transport properties of the superconducting Indium/Bi2Te3 interface where Andreev reflection plays a key role.
