Rate My Professor Roger Reeves

Reeves' research expertise lies in the growth, structure, and optical/electronic characterisation of semiconductor thin films, with a particular emphasis on transparent conducting oxides and wide band-gap oxide semiconductors such as tin oxide (SnO₂) and gallium oxide (Ga₂O₃). His work explores sol-gel methods, doping effects, annealing processes, and surface chemistry, enabling applications in next-generation photovoltaics including perovskite and wavelength-selective solar cells, advanced sensors for environmental and health monitoring, catalysts for carbon capture and water purification, and UV photodetectors critical for skin cancer prevention. As an Emeritus Investigator at the MacDiarmid Institute for Advanced Materials and Nanotechnology, Reeves has made substantial contributions to oxide semiconductor research, fostering key international collaborations and enhancing the institute's international reputation. Notable publications include "Growth and properties of Sn-doped sol-gel Ga₂O₃ thin films" (Journal of Vacuum Science & Technology A, 2025), "Optical and electronic properties of high quality Sb-doped SnO₂" (Journal of Applied Physics, 126, 135702, 2019), an article in Physical Review Letters (122, 25, 2019), "Synchrotron X-ray Photoelectron Spectroscopy Study of Surface Chemistry of Oxide Semiconductors" (J. Phys. Chem. C, 2018), and "Improving Charge Transport in Perovskite Solar Cells" (Inorganics, 2024). In recognition of his research excellence, he was awarded the T.K. Sidey Medal by the Royal Society Te Apārangi in 2007 while serving as Associate Professor. Reeves also supervises postgraduate students at Master's and doctoral levels and has been involved in course coordination.
