THE EFFECT OF TRIANGULAR CAVITIES ON PIEZOELECTRIC PROPERTY OF GRAPHENE

Abstract
Piezoelectricity is a unique material property that converts mechanical energy to electrical one or vice versa. In order to call a matter piezoelectric, it should be in non-centrosymmetric structure and have sufficiently large band gap. Graphene has none of these properties in its natural composition. It is shown that, coaxing the graphene structure can give piezoelectric property to this non-piezoelectric material. In this study, the size effect of the triangular holes and their placements on the structure to the piezoelectricity are investigated theoretically via density functional theory based calculations. According to the calculation results, while the size of the cavity effects the piezoelectricity, layout of the similar shaped triangular cavities do not change the piezoelectric coefficient.
