This article presents careful optimisation of the gas composition for preparation of boron doped nano-crystalline diamond layers using microwave plasma enhanced linear antenna chemical vapour deposition apparatus. By radically increasing the B content and careful consideration of the O content in the gas phase, boron doped diamond layers were prepared over large areas with high boron concentrations and electrical conductivity levels akin to boron doped diamond layers prepared in conventional MW PECVD systems with electrochemical properties suitable for industrial applications.
