The process involves using a gas-to-particle conver...

The role of nitrogen doping on the development of visible light-induced photocatalytic activity in thin TiO2 films grown on glass by chemical vapour deposition. Journal of Photochemistry and Photobiology A: Chemistry, 179(1-2), 213-223. https://doi.org/10.1016/j.jphotochem.2005.08.018

A brief review of the findings of a range of studies aimed at describing the influence of the N-doping of TiO2 thin films and particles on possible visible light induced photoactivity is presented. By way of a new approach to the direct growth of N-...

Photonic band gap properties of GaP opals with a new topology (2005)
Journal Article
Palacios-Lidón, E., Yates, H., Pemble, M., & López, C. (2005). Photonic band gap properties of GaP opals with a new topology. https://doi.org/10.1007/s00340-005-1821-6

In this paper, we propose that the “anomalous” optical response exhibited by GaP and InP infiltrated opals is due to the peculiar morphology shown by these materials when grown within the pores. In order to account for their optical response, we prop... Read More about Photonic band gap properties of GaP opals with a new topology.

Modification of the natural photonic bandgap of synthetic opals via infilling with crystalline InP (2005)
Journal Article

Modification of the natural photonic bandgap of synthetic opals via infilling with crystalline InP. Advanced functional materials, 15(3), 411-417. https://doi.org/10.1002/adfm.200400248

The growth of high-quality stoichiometric indium phosphide by atmospheric pressure metal±organic chemical vapor deposition within thin-film artificial opals has been optimized. The optical properties of these systems have been studied as a function... Read More about Modification of the natural photonic bandgap of synthetic opals via infilling with crystalline InP.

Growth and formation of inverse GaP and InP opals (2003)
Journal Article
Yates, H., Whitehead, D., Nolan, M., Pemble, M., Palacios-Lidón, E., Rubio, S., …López, C. (2003). Growth and formation of inverse GaP and InP opals

Opals consist of an ordered array of SiO2 spheres. This leads to a modulation of the refractive index and hence photonic stop bands behaviour over the visible/IR range of the electro-magnetic spectrum. The exact position of the stop bands depends on... Read More about Growth and formation of inverse GaP and InP opals.

Comparing lead iodide and lead acetate based perovskite absorber layers by aerosol-assisted chemical vapor deposition
Presentation / Conference
Afzaal, M., Basak, S., & Yates, H. Comparing lead iodide and lead acetate based perovskite absorber layers by aerosol-assisted chemical vapor deposition. Presented at 2020 Advances in Science and Engineering Technology International Conferences, Dubai, United Arab Emirates

Aerosol-assisted chemical vapor deposition at atmospheric conditions has been used to deposit optically active lead perovskite thin films. Lead iodide and lead acetate trihydrate precursors were used and the resulting films compared. X-ray powder di...

The effects of TCO properties on all-electrodeposited CdS/CdTe PV solar cells
Presentation / Conference
Yates, H., Sheel, D., Dharmadasa, I., Echendu, O., & Fauzi, F. The effects of TCO properties on all-electrodeposited CdS/CdTe PV solar cells. Presented at PVSAT-9 9th Photovoltaic Science, Applications and Technology Conference, Swansea, UK

There is increased drive to produce renewable clean energy sources, which has led in recent years to the rapid rise of alternatives such as solar PV technology. For a commercially viable product, the PV cells must be of high efficiency along with the... Read More about The effects of TCO properties on all-electrodeposited CdS/CdTe PV solar cells.
