The fabrication of ultramicroelectrodes (UMEs) for analytical electrochemical applications has been explored, using boron-doped diamond as the active electrode material in an insulating coating formed by deposition of electrophoretic paint. Because of the rough nature of the diamond film, the property of such coatings that is normally exploited in the fabrication of UMEs, namely the tendency to...

Distinct improvement in adhesion of diamond coatings on hard metal substrates was achieved by following substrate surface pretreatment [I]: First WC was removed from the substrate surface by etching with Murakami solution (K3[Fe(CN)6] in KOH), after which the Co binder network was etched with H2S04/H202 solution. Then diamond coatings were deposited on the substrates by hot-filament CVD. Appare...

We investigated the metal-diamond interface formation and the growth of chromium thin films as contact material on diamonds, which should help to improve single-crystal diamond (SCD) particle detectors. As shown previously [1], we are able to derive information about metal film conductivity by means of infrared spectroscopy (IRS) and analysing the data with a Drude type dielectric function. In ...

Single-crystal CVD diamond (scCVDD) for detector applications is grown on best quality HPHT single-crystal diamond substrates of (100) crystallographic orientation, because the incorporation of stacking faults or the creation of twin crystals is hereby more suppressed than, e.g., in the (111) growth direction. Any imperfection of the substrate may hand over in the CVD diamond film either as iso...
