h-BN encapsulation of atomically thin layers of PtTe<sub>2</sub> for electronic transport measurements at low temperatures

ORAL

Abstract

PtTe2 is an air-stable exfoliatable Dirac semimetal that features two different types of Dirac excitations. When reduced to a single triatomic layer, PtTe2 becomes a semiconductor, leading to applications that may exploit the Schottky barrier formed at the interface with a metallic van der Waals material, such as, fast switching, power rectification and solar cells. Here, we present details on the h-BN encapsulation of PtTe2 and the obtention of an electronic device through standard nanofabrication methods. Additionally, we present our current efforts on device fabrication of Cr alloys of PtTe2, known to present a magnetic ordering transition at relatively high temperatures.
