WebJun 22, 2024 · In this work, we predict that monolayer Janus transition metal dichalcogenides (JTMDs) in the 1T′ phase possess colossal nonlinear photoconductivity owing to their topological band mixing, strong inversion symmetry breaking, and small electronic bandgap. 1T′ JTMDs have inverted bandgaps on the order of 10 meV and are … WebMar 23, 2024 · Thus, a 2-dimensional transition metal dichalcogenides (MoTe2) is preferred for designing the device structure. The back-gate technique is used for better-controlled channel operation. The effect of variation in the work function and length of back-gate and density of interface trap charge on device performance is investigated. WebNov 1, 2024 · Previously, the ambipolar MoTe 2 has turned into unipolar p-type by utilizing high work function metallic electrodes e.g. platinum [31]. But, unipolar n-type behavior is very difficult to achieve, this is owing to combination of Fermi-level pinning and limited use of low work function contacts [32]. taursham park taverham
