摘要
We report point-contact spectroscopic studies on high quality single crystalline beta-PdBi2 with a superconducting T-c = 5.2 K. Our measurements showa typical double-peak structure in the voltage-biased junction conductance at low temperatures, probably excluding the existence of topological Andreev bound states. The conductance curves can be well fitted with the standard Blonder-Tinkham-Klapwijk model for s-wave superconductors, yielding a superconducting gap Delta(0) similar or equal to 0.
