Micro-strip sensors based on CVD diamond

Laser Micro-Raman Spectroscopy of CVD Nanocrystalline Diamond Thin Film

Laser micro-Raman spectroscopy is an ideal tool for assessment and characterization of various types of carbon-based materials. Due to its special optical properties (CrN) coated stainless steel substrates. NCD films have been investigated by laser micro-Raman spectroscopy. The fingerprint of diamond based materials is in the spectral region of 1000-1600 cm-1 in the first order of Raman scatter...

Superconductivity in CVD diamond films.

A beautiful jewel of diamond is insulator. However, boron doping can induce semiconductive, metallic and superconducting properties in diamond. When the boron concentration is tuned over 3 × 10(20) cm(-3), diamonds enter the metallic region and show superconductivity at low temperatures. The metal-insulator transition and superconductivity are analyzed using ARPES, XAS, NMR, IXS, transport and ...

On the occurrence of {113} facets on CVD-grown diamond

Ae Monitoring from Cvd-diamond Film Subjected to Micro-indentation and Pulse Laser Spallation

We monitored AEs during micro-indentation and pulse laser spallation test of CVD diamond film deposited on sintered SiC, and classified the fracture type by Lamb wave AE analysis. In the indentation test with a Rockwell sphere indenter, we observed Hertz ring cracks and simultaneously detected AEs from Mode-I fracture. Crack types were classified from polarity distribution of the first arrival ...

Characterisation of Single-Crystal CVD-Diamond Detectors

Recently, the quality of intrinsic CVD Diamond (CVD-D) has tremendously been improved. The replacement of the previous used silicon substrates for growth by ultra-pure HPHT Single-Crystal (SC) {100}-oriented diamond provides homo-epitaxial grown material almost free of structural defects. Nevertheless, all substrates nominally {100}oriented show a certain amount of off-angle declination from th...
