Evidence of shallow bandgap in ultra-thin 1T'-MoTe2 via infrared spectroscopy

Jin Cheol Park, Eilho Jung, Sangyun Lee +2

Although van der Waals (vdW) layered MoS2 shows the phase transformation from the semiconducting 2H-phase to the metallic 1T-phase through chemical lithium intercalation, vdW MoTe2…
