Diamond – a multi-facetted material - Professor Oliver Williams
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.
