Topological semiconductors resonate with an elusive form of radiation

The aims of the project are to fill a substantial knowledge gap in a class of novel semiconductors that can function as sensors in a frequency range where conventional semiconductors do not work. The way these materials interact with light is not fully understood. The project expects to provide this understanding of great significance and generate new knowledge in physics and materials science. Expected outcomes include a results database that will guide experiments and enable future sensor design. The project expects to provide substantial benefits by identifying the best materials for use as sensors in this frequency range, which has applications in communications, defence, and in the Science and Research Priorities of Food and Transport.
