David Mowbray

Professor David Mowbray is a Professor of Physics at the University of Sheffield, affiliated with the School of Mathematical and Physical Sciences and the Department of Physics. His research focuses on III-V semiconductors, quantum dots, and nanostructures, emphasizing applications in high-efficiency lasers and light emitters. He has pioneered studies on AlGaInP band structures and quantum dot-based devices, including lasers on Si substrates for silicon integration.

Qualifications: B.A. in Physics (Hertford College, Oxford, 1984) and D.Phil. in Physics (Hertford College, Oxford, 1989).

Research interests include optical spectroscopy of wide band gap materials (AlGaInP, AlInGaN) for visible/UV emitters, quantum dot lasers with low threshold currents, and nanowire quantum dots for single-photon sources. Current projects involve quantum dots in quantum wires with UCL and Warwick, aiming for nanoscale lasers and efficient photon sources.

Teaching includes courses on Fourier Techniques, Electromagnetism, and nanotechnology. He has held leadership roles, such as Head of Department and Senior Tutor, and serves on professional committees like the Institute of Physics Degree Accreditation Committee.

Grants include EPSRC funding for quantum dot lasers on Si (2012–2016) and nanowire quantum dots for silicon-based emitters (2016–2020). His work bridges semiconductor physics, nanostructure engineering, and optoelectronic device applications.
