Research

Our current research interests are:

1) Multi-scale modeling of devices based on 2D materials heterostructures

The goal of this activity is to build a multi-scale modeling framework for studying the electron transport in 2D materials heterostructures and design devices with enhanced functionality.

2) Device simulations of 2D materials-based logic and memory devices

In this activity, we focus on designing the MOSFETs and RRAM devices using the device simulation tools. To increase the efficiency of device design, simulation decks in commercial TCAD tools are built. The TCAD models are then validated with the atomistic simulations and reported experimental data.

3) Bridging predictions to the experimental demonstrations

Here, our objective is to develop simple intuitive analytical models which can be easily used by both experimentalists who want to understand how to design better experiments and circuit designers who want to understand the limitations of a novel technology on the performance of the ideal device. These simple models can always be further refined with more experimental data and calculations from the first-principle simulations. Currently, we are investigating experimentally observed memristive behavior of 2D materials-based metal-insulator-metal structures.

4) Design of unconventional computing devices e.g. qubit, bio-inspired devices

This activity will focus on the multi-scale modeling of non-charge-based computing devices.
