Diamond CVD onto different substrates
We are studying the problems associated with growing diamond on a range of different substrate materials. These include standard materials like Si, as well as more novel ones, such as Ti, Ge, W, WC-Co, SiC, SiO2, B4C, GaN and steels. For the latter we are investigating the use of barrier layers to increase adhesion and prevent graphitisation.
