Tunable Electronic and Dielectric Properties of …

Abstract. We report tunability in electronic and dielectric properties of a technologically promising nanomaterial MoS 2.The properties of MoS 2 can be tuned by varying the layer thickness, by applying mechanic strain, by tuning the interlayer distance, and by applying external electric field. Reducing the slab thickness systematically from bulk to monolayers causes blue shift in the band gap ...
