Inhomogeneous superconductivity in PdTe2

ORAL

Abstract

PdTe2 is a type II Dirac semimetal which also shows superconductivity below 1.7 K. We have performed scanning tunneling microscopy and spectroscopy on single crystals of PdTe2 and have shown that despite such unique co-existence of Dirac physics and superconductivity, the superconducting phase of PdTe2 is conventional in nature. As revealed by our magnetic field dependent STM experiments, the single crystals of PdTe2 display a type I-like behavior at certain points and type-II like behavior at certain other points. We will discuss the details of this inhomogeneous superconducting phase and comment on its relationship with the intrinsic electronic inhomogeneity that was also detected in the normal state of PdTe2.
