Short Description

The goal of this thesis is to extend the functionality of a state of the art industrial quantum transport solver based on the effective mass approximation to include scattering mechanisms for 2D materials and generally devices that are periodic in at least one of the three spacial dimensions.

The Big Picture

The piezoelectric materials, which can convert mechanical energy to electrical energy and vice-versa, have found multiple applications in sensors, actuators, and harvesting energy from the environment. The most popular material being lead zirconate titanate (PZT). Recently, monolayer two-dimensional (2D) materials have been both theoretically predicted and experimentally demonstrated to be piezoelectric unlike their bulk counterpart due to the absence of centro-symmetry1. However, the use of this piezoelectricity in building nanoscale devices is still lacking.Hence, in this project, you will have scope of proposing novel devices using the intrinsic piezoelectricity in monolayer 2D materials.
