Overview

Two-dimensional (2D) ferroelectric materials have attracted considerable interest in recent years. This fast developing research field holds great promise for discovering novel materials for applications in non-volatile storages.

However, the scarcity of suitable ferroic materials and convoluted physics mechanisms have greatly hindered progress.

The aim of this project is to:

  • identify new families of 2D ferroelectric materials
  • explore the physics stemming from interactions between ferroelectricity and ferromagnetism
  • propose multifunctional applications based on computational simulations.

These investigations will not only be of fundamental scientific importance, but also lay key foundations for new electronics design and implementation.

Research activities

As part of the research project, you will be tasked with the following:

  • Design 2D hybrid multiferroics by integrating ferromagnetic and ferroelectric-layered components.
  • Develop tunable magnetic states controlled by ferroelectric switching.
  • Explore 2D ferroelectric topological insulators that both possess superior topologically-protected edge states and switchable polarisation based on multilayer ferroelectric layers.
  • Develop novel approaches for controlling topological phase transitions via ferroelectric switching.
  • Construct conceptual blueprints for multifunctional electronic devices with fast switching speed and low-energy consumption based on hybrid multiferroics and ferroelectric topological insulators.

Outcomes

As a result of this project we expect to create high-impact publications and patents.
