Charge density wave phase transitions in Tantalum Disulfide*

The discovery of transition metal dichalcogenides has reopened the interest in charge density wave physics. By looking at the phase transition properties, it is possible to create switches with properties exceeding the traditional FET’s. In this work, we fabricated 2D nanoscale switches made of 1T-TaS2 and graphene. We tested the transport properties between the Mott insulating state and the conductive state of the switch. Our work will provide insight on possibilities for the production of ideal switches and transistor logic.
