Overview

Organic electronic materials based on small molecules have a range of interesting applications: they enable lightweight, flexible devices that can be biodegradable and very cheap to manufacture.

One challenge working with small molecules controlling how they crystallise into a film, since this affects the electronic properties of the resulting device. Since a wide range of parameters affect the way the film crystallises, this can be a complex problem to understand and control.

The aim of this project will be to investigate the relationship between the way a molecular film is processed, its structure and its electronic properties.

Research activities

This project will make use of a range of QUT's cutting-edge equipment for materials characterisation.

The focus of the work will be on using atomic force microscopy (AFM) to visualise the structure of the film with molecular-level detail, and then to measure the electronic gap of the film using a combination of ultraviolet photoelectron spectroscopy (UPS) and inverse photoelectron spectroscopy (IPES).

This will provide the HOMO-LUMO gap, a key indicator of electronic behaviour.

Outcomes

This project will help us understand how processing conditions affect resulting molecular film. Depending on your interests, we will investigate different processing conditions including:

  • solvent
  • temperature
  • deposition method
  • post-processing.

The outcome will be a new understanding about creating better films for applications in electronics.
