Our group's main interests have been in making optical measurements on wide-bandgap semiconductors and low-dimensional systems such as quantum dots, wires and wells.
Advanced Functional Materials and Devices (AFMD) Group
We are working on advanced functional materials and devices, in particular those based on organic semiconductors and for photovoltaic applications.
Photovoltaic and optoelectronic device group
The Photovoltaic and Optoelectronic device group is led by Prof Henry Snaith. Our main interest is in metal halide perovskites for photovoltaic and light emitting applications.
Computational Condensed Matter Physics Group
We use and develop upon first principles computational modeling methods such as density functional theory and many-body perturbation theory to understand and predict structural, vibrational, electronic, optical and transport properties of materials.
Johnston Research Group
Research in the Herz group explores the fundamental science and applications of semiconducting materials and nanostructures ranging from organic molecules and solids, III-V inorganic semiconductors & nanostructures, to hybrid metal halide perovskites.
