  • Polycrystalline Diamond - an overview

    Polycrystalline Diamond. Polycrystalline diamond (PCD) has been extensively explored as a radiation detector, particularly to exploit its radiation hardness as, for example, in large detector assemblies (Adam et al., 2000) where the inhospitable environment does not permit conventional materials to survive for the periods desired.

    2014-3-15 · In this paper, the growth of polycrystalline chemical vapour deposition (CVD) diamond thin films on fused silica optical fibres has been investigated. The research results show that the effective substrate seeding process can lower defect nucleation, and it simultaneously increases surface encapsulation. However, the growth process on glass requires high seeding density. The effects of ...
