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.

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

2D materials have seen a surge of interest in recent years for their advantageous electronic properties. For industrial applications, devices need to be able to be simulated quickly and accurately. Full-band and/or Density Functional Theory (DFT) models are usually too computationally demanding. A similar case can be made for FinFETs, which are 3D components that can be approximated as 2D slices, where the high dimension can be treated as periodic
