The Johnston Group is a research group within the sub-department of Condensed Matter Physics, which is part of the sub-faculty of Physics at the University of Oxford. Our current research may be divided into three themes (i) Semiconductor nanowires (ii) Terahertz photonic technologies and (iii) Vapour deposited Perovskite materials for photovoltaic applications.
