Book Description
This report summarizes results of Navy contracts with Raytheon Research Division, Texas Instruments, and Norton Company for the development of chemical-vapor-deposited (CVD) optical-quality bulk diamond from October 1990 through April 1993 and characterization through December 1993. Clear windows with thickness of 0.3 to 1.0 millimeter (mm) and diameters up to 25 mm were produced. In the 8-to-14 micrometer infrared region, the absorption coefficient was as low as 0.1 to 0.3 cm( -1), optical scatter was below 1% and emissivity was below 3% at 500 deg C for 0.5-to-1 mm thick samples. Microwave dielectric properties, thermal properties, and most mechanical properties of chemical- vapor-deposited diamond were equivalent to those of Type IIa natural diamond. The mechanical strength of 0.5-to-1 mm thick CVD diamond attained so far is an order of magnitude lower than of natural diamond and is governed by microscopic cracks and detects.

Book Description
Here, leading scientists report on why and how diamond can be optimized for applications in bioelectronic and electronics. They cover such topics as growth techniques, new and conventional doping mechanisms, superconductivity in diamond, and excitonic properties, while application aspects include quantum electronics at room temperature, biosensors as well as diamond nanocantilevers and SAWs. Written in a review style to make the topic accessible for a wider community of scientists working in interdisciplinary fields with backgrounds in physics, chemistry, biology and engineering, this is essential reading for everyone working in environments that involve conventional electronics, biotechnology, quantum computing, quantum cryptography, superconductivity and light emission from highly excited excitonic systems.
