Electrical characteristics of the WS2/SnS2 tunneling transistor. (a) Measured transfer characteristics of the bottom-gated WS2/SnS2 tunneling transistor. The on-state current (ION) is 3.7 μA with an area of 20 μm2 and on/off current ratio is over 106. (b) Measured temperature characteristics of the bottom-gated WS2/SnS2 tunneling transistor.
