概要

論文の詳細を見る
The diamond has highest properties amongst all the materials, such as elastic constant (hard-ness), thermal conductivity, transparency to optical wave and X-ray, wide bandgap semiconductor, and negative electron affinity, which lead to various kinds of applications in electronics industries. Heat sinks of laser diode for optical communication, surface acoustic wave devices for optical, wireless communication and oscillator applications have been already commercialized. The active devices such as high power transistors, electron emitters are the hopeful candidates for near future applications. The another applications such as tools, speaker diaphragms, optical windows, X-ray windows and sensors as well as electrode for electro-chemical applications are briefly introduced. According to the recent successful development of the technology of vapor phase growth, the large size diamond is ready to be provided with low manufacturing cost.
