PhD Projects available

Project 1 Emerging Electronics

The rise of novel semiconducting materials provides a vision for the future is to move beyond the existing applications and explore new realms of electronic use rather than replacing existing silicon-based electronics. These materials often expanded the electronic landscape making it more functional, accessible, and sustainable. The focus of this research project is developing emerging electronic materials in four main types of existing applications: electronics, optoelectronics and sensors. This will involve material processing strategies, device architectures, understanding the basics of charge transport and optical mechanism and their applications.

Project 2 Organic light-emitting devices and lasers

Organic semiconductor materials combine novel optoelectronic properties with simple fabrication and the scope for tuning the chemical structure to give desired applications makes them attractive for low cost, flexible, biocompatible and stretchable microelectronic systems that go beyond the scope of conventional electronics. The goal of this PhD project is to develop novel types of organic optoelectronic devices (i.e. light-emitting transistors, light-emitting diodes) to probe the dynamics of material combinations, device architectures in high-frequency electro-optical measurements.

Project 3 Bioelectronics

The focus of this project is interfacing electronics with biological systems. The aim is to develop an understanding of the fundamental processes that take place at the abiotic/biotic interface and to develop better tools for biomedical applications. More specifically, the project involves the use of biological and bio-inspired materials in bio-molecular electronic devices such as an organic electrochemical transistor (OECT), in which the drain current is controlled by the injection of ions into a conductor or semiconductor thin-film channel.

Project 4 Sustainable electronic materials

The project involves the development of sustainable, biodegradable electronics devices. Organic and biomaterials have the potential for greater sustainability that extends across the entire life cycle of electronics, beginning with the use of materials that are synthesized, rather than mined from the earth, and ending with potentially biodegradable or recyclable devices. It is not just the devices themselves that promise to be more eco-friendly than silicon-based electronics, but also their manufacture.
