Nonreciprocal charge transport in topological superconductor candidate Bi2Te3/PdTe2 heterostructure

npj Quantum Materials, 2022
In a hybrid system of topological insulator (TI)/superconductor (SC), the proximity-induced topological superconductivity is expected to appear at the interface. Here we propose and demonstrate that a TI/SC hybrid Bi2Te3/PdTe2 heterostructure serves as a
