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.
