Fabrication of planar tunnel junctions on bulk Pb<sub>1-x</sub>Sn<sub>x</sub>Se

ORAL

Abstract

The topological crystalline insulator Pb1-xSnxSe can undergo a trivial to non-trivial transition as a function of temperature or pressure. Angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling spectroscopy (STS) are both useful measurements for studying the nature of these topological transitions. However, ARPES and STS are incompatible with high pressure conditions. Planar tunneling spectroscopy (PTS) can provide similar information as STS but can be deployed at high pressure. I will discuss our efforts to fabricate Pb-alumina-Pb1-xSnxSe planar tunnel junctions and will present the results obtained thus far.
