Strain-dependent modulation of conductivity in single-layer transition-metal dichalcogenides
Quantum conductance calculations on the mechanically deformed monolayers of MoS${}_{2}$ and WS${}_{2}$ were performed using the nonequlibrium Green's functions method combined with the Landauer-B\"uttiker approach for ballistic transport together with the density-functional-based tight binding method. Tensile strain causes significant changes in the electronic structure of transition-metal dichalcogenide single layers and …
