The dual aims of this departmental seminar are to give an overview of prior work on nanostructuring silicon and planned collaborative work within the Nanophysics Group relating to silicon-metal nanocomposites and nanoporous metals. Nanostructuring silicon can endow the semiconductor with tunable properties such as efficient visible light emission, ultralow thermal conductivity, and medical biodegradability. Under photoexcitation, the ensemble luminescent quantum yield has continuously been improved over the last 25 years and can now exceed 60%. Potential uses include medical imaging, solar cells and sensing. The medical biocompatibility has been clinically translated in brachytherapy (highly targeted radiotherapy). Biodegradability underpins much pre-clinical research on nano-Si worldwide in drug delivery, theranostics and tissue engineering. We plan to investigate a template-based approach to biodegradable metal-Si nanocomposites and nanoporous metals, highlighting potential medical uses in photothermal therapy of cancer that exploit their plasmonic and thermal properties.
