Probing CDW states in Graphene/1T-TaS2 heterostructures using Scanning Tunneling Microscopy/Spectroscopy.

ORAL

Abstract

The transition-metal dichalcogenide 1T-Tantalum Disulfide (1T-TaS2) hosts various

Charge Density Wave (CDW) states which survive well above room temperature.

However, 1T-TaS2 is highly susceptible to degradation under ambient conditions,

making it difficult to probe experimentally with surface sensitive techniques. We use a

monolayer Graphene cover to protect its surface from oxidation and investigate these

heterostructures using Scanning Tunneling Microscopy/Spectroscopy. Our

measurements reveal an induced CDW-like phase in the Graphene layer.
