Diamond quantum dots fabricated by ion implantation

Abstract

For centuries scientists have been fascinated by the 'alchemy' of transforming carbon into diamond. This project aims to fabricate diamond nanocrystals embedded in a glass matrix by direct carbon ion implantation followed by thermal annealing. Unlike other methods of making diamond, the coalescence of carbon into diamond occurs under heating in a conventional furnace and does not require the application of high external pressures or any pre-existing diamond template. We outline a scheme to exploit the properties of these crystals for novel applications in quantum devices.
