Temperature-Dependent Logic Behavior of Logic Transistors Based on WS<sub>2</sub>
With the advantages of two-dimensional (2D) materials, the small footprint logic transistor architecture can realize the primary logic function (OR and AND) in a single cell. Compared with silicon transistors, the logic transistor is expected to be a competitive candidate for next-generation electro...

With the advantages of two-dimensional (2D) materials, the small footprint logic transistor architecture can realize the primary logic function (OR and AND) in a single cell. Compared with silicon transistors, the logic transistor is expected to be a competitive candidate for next-generation electronic technology with distinct functions and high area-efficiency. We report on the fabrication of logic transistors based on WS<sub>2</sub> using the new architecture and the investigation of the temperature-dependent logic behavior. Notably, the device shows general trends of logic function on different operating voltages and switches AND logic to OR logic from low temperatures to high temperatures. We also measured the transport properties of the WS<sub>2</sub> logic transistors at different temperatures to demonstrate our theoretical analysis. The threshold voltage, saturation current, and field-effect mobility are extracted from transport characteristics, which is in line with our mechanism explanation. This work reveals that temperature is of much significance to the logic function of logic transistors. |
