Multifunctional piezoelectric sensors using two-dimensional layered materials

The project envisages the development of multifunctional piezoelectric sensors using two-dimensional (2-D) layered materials. Piezoelectricity is defined as the electrical response of the materials with respect to the mechanical actuation. This property persists in the materials that have non-centrosymmetry in their internal structure.In particular, the 2-D materials with the non-centrosymmetric structure a great potential lies in the field of electromechanical and electronic device applications owing to a large area coverage. One such class are transition metal dichalcogenides (TMDCs) . TMDCs contain one metal and two chalcogen atoms thus providing non-centrosymmetry in the monolayer . Our target is to explore monolayer of TMDCs by sandwiching it in between two graphene conductive electrodes to obtain a semiconductor device that is capable of sensing strain , actuation applications and energy generation using piezoelectric phenomena.
