CVD diamond: a new technology for the future?
نویسنده
چکیده
Diamond exhibits a unique range of properties including extreme hardness, mechanical strength, high thermal conductivity, broad-spectrum optical transparency, electrical insulating properties, and chemical resistance. However, its high cost and problems in manipulation have hitherto made it difficult to realize this potential. This situation has dramatically changed with the advent of techniques to confer the properties of diamond on a variety of substrates by depositing very thin diamond films on to them.

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...
متن کاملConference Report: WORKSHOP ON CHARACTERIZING DIAMOND FILMS II Gaithersburg, MD February 24–25, 1993
The second in a series of workshops was held at NIST on February 24-25, 1993 to discuss in depth specific topics deemed important to the characterization of diamond films made by chemical vapor deposition (CVD) and to address the need for standards in diamond technology. The topics chosen for this workshop were based on feedback from the attenders of the first workshop [1]. The audience targete...
متن کاملA 3D tomographic EBSD analysis of a CVD diamond thin film.
We have studied the nucleation and growth processes in a chemical vapor deposition (CVD) diamond film using a tomographic electron backscattering diffraction method (3D EBSD). The approach is based on the combination of a focused ion beam (FIB) unit for serial sectioning in conjunction with high-resolution EBSD. Individual diamond grains were investigated in 3-dimensions particularly with regar...
متن کاملDesigning Optimal Bias Voltage for Radiotherapy Diamond Dosimeter
Introduction: Recent developments of radiotherapy techniques, require high accuracy detectors to determine the delivered dose in a small area. Chemical vapor deposition (CVD) or naturally growth diamond detectors which are commercially available are good candidates for this purpose. In these detectors two electrodes with high different electrical potential are deposited on both...

For future particle accelerator experiments, e.g. at FAIR, we are developing novel, advanced diamond sensors grown by chemical vapour deposition (CVD), capable on one hand of replacing the commonly used silicon tracking devices and being on the other hand an advantageous alternative to polycrystalline or single-crystal diamond sensors used so far in beam diagnostics and timing applications. By ...
