Abstract
Diamond is best known as a mined gemstone and the hardest material known but it is far more common in our everyday lives than most people appreciate. The 1km or wire in your car (or 140km in a 747 aircraft) are drawn through diamonds, deep sea drilling is diamond enabled and machining, concrete cutting etc are all enhanced by lab grown diamond. The superlative hardness of this material originates from its atomic density, and this results in many other extreme properties such as unrivalled thermal conductivity and sound wave velocity in the material. These properties are driving new applications such as thermal management of semiconductors, ultra-high frequency filters for 5G communications and Quantum Technologies. This lecture aims to introduce the uninitiated into this material and demonstrate some of its key developments in the last ten years.

Biography
Oliver Williams received his BEng in 1998 and PhD in 2003, both from University College London. He then worked as a postdoc at Argonne National Laboratory USA, followed by IMO/IMEC Belgium. In 2008 he received the Fraunhofer “Attract” award at the Fraunhofer Institute for Applied Solid State Research in Freiburg, Germany where he ran their Diamond Technology team for three years. He came to Cardiff School of Physics and Astronomy as Reader in 2011 with a Marie Curie Fellowship and became Professor in 2015. He was Director of Research 2018-2023 and currently head of Quantum Materials. His research group, Cardiff Diamond Foundry, focuses on diamond growth and integration for net zero and quantum technologies.
