Research interests

Dr. Yun Liu's group aims to use materials chemistry as a tool to design and develop novel functional materials for uses in electronic components, smart devices, energy conversion and storage.

The main research direction is to explore the correlation between defect clusters, local structure and property of functional polar materials though various spectral techniques (e.g. ERS and XPS) and diffraction techniques (including electron diffraction, neutron diffraction and synchrotron radiation), and then to design new materials or further optimize/develop the materials with novel functions for uses in charge/energy storage, photocatalysis, solar cells, including traditional lead-free ferroelectric and piezoelectric materials for uses in sensors, actuators and transducers etc.

She is also interested in the researches related to nanomaterials and 2D materials in both synthesis and characterisation.

General Guidance of the research directions for potential PhD students

Functional Materials research is a multidisciplinary area. We welcome the students, who have different background knowledge and skills (Materials chemistryApplied Physics, Computational chemistry and physics of Solids  Materials Science and Engineering) with strong innovative and creative capabilities, to join us and to work on one of the following potential fields:

Fundamental Research: 

  • Materials chemistry: building an interaction between the local/average structure and property of functional materials at the different length scales via X-ray diffraction, electron diffraction, neutron diffraction/scattering,  guiding design and development of new functional materials
  • Defect chemistry and computational chemistry: novel defect cluster design for the development of new functional materials, enriching defect chemistry theory in solids and guiding novel materials design.
  • Electrochemistry: Development of novel polar functional materials for use in renewable and green environment.   

Applied Research:

  • New materials: photocatalysts, photovoltaic materials, colossal permittivity materials, T-Hz dielectric materials, photoluminescent materials, electro-optic and optic-electric materials, muitferroic/ferroelectric and piezoelectric materials with different forms (e.g. nano particles, 2D, thin films, ceramics and crystals).
  • New devices: capacitors, energy storage devices, power storage devices, energy conversion and harvesting devices, pulse powder controllers, bi/sensors, actuators and transducers.

Specific project available now

1, An industry project for a potential PhD candidate in the field of materials science and engineering:  The PhD scholarship is available instantly for the development of the new generation, high frequency dielectric materials.

Suitable students: materials science and engineering, applied physics and materials chemistry

2, Computational chemistry (co-supervised): this project provides an absolutely fantastic opportunity for the student who is very keen in using computational chemistry to solve experimental problem. This will be a joint co-supervised project (Principle supervisor in computational chemistry- Dr Terry Frankcombe, ADFA, UNSW and co-supervisor in materials chemistry- Prof Yun Liu, RSC, ANU). The student will be registered at ADFA, UNSW with an instantly available PhD scholarship to work in a very friendly and collaborative environment.

Suitable students: Theoretical and computational chemistry/physics, Physics, Applied Mathematics, and Materials Chemistry

2, Fabrication and characterisation of 2D and 3D structured functional thin films

We have a start-of-the art deposition facility that combines pulse electron beam and pulse laser together to provide both PED and PLD functions within one chamber, allowing to construct 2D and 3D structured thin films using metals, metal oxides, non-oxides, organic materials and polymers, including photovoltaic thin films for sole cells, photocatalytic thin films to split water for hydrogen generation.

Suitable students: Applied/Physics, Materials Science and Engineering, Nanomaterials and Nanotechnology

3, Synthesis, structure and property characterisation photo-excited functional materials for energy conversion

The research can cover one of photovoltaic, photocatalytic, optoelectric and electroptic materials.  The materials will be synthesised using either solid state reaction or wet chemical method like Sol-gel and hydrothermal reaction. Defect analysis, local/average structure and properties/functions of the resultant materials will be investigation at different lengths scale to build a correlation between chemical composition, structure and properties/functions.  Some research will expand to the fabrication of devices for practical application.

Suitable students: Materials Chemistry, physical chemistry Applied/Physics, Materials Science and Engineering, Nanomaterials and Nanotechnology

 

4, Preparation, structure and property of polar functional materials

This research direction will cover the dielectric, ferroelectric, piezoelectric and mutiferroic materials. The core research strategy is to figure out the strong correlation between the defect/local structure and polarisation-related properties. The X-ray diffraction, electron diffraction and in situ (with external force, i.e. electric field and pressure) neutron diffraction as well as neutron Inelastic and quasielastic scattering will be the main tools to investigate local structure, phase transition and structured evolution as well as dynamic phonon behaviour. Various spectral analyses and property characterisations at different-lengths scale will be also investigated to build a real structure –property relation of the complicated, polar functional materials

This project aims to discover new materials that provide a solution for high density energy storage in the form of solids. The research also includes the fundamental research using the techniques abovementioned to establish the correlation between chemical compositions, defects, local and average structure, and property; and to understand the mechanism behind the energy storage capability; and subsequently to develop new, high performance energy storage materials and devices.

6, Dielectric materials and devices for next generation electronic technology and microwave communication

This direction targets the practical application, and has a strong link with industry partners. The research includes both fundamental and applied research activities.
