| Abstract(in English) | There is a long history of research on new electrically conductive materials aiming at new technologies which might follow the fully matured silicon technology. Following the proposal on the concept of "organic semiconductor" by Prof. Hiroo Inokuchi of Tokyo University (1954), studies on the photoconductivity of organic semiconductors in early 1 960's have become profitable as the big business of organic photoconductors (OPCs) adopted in copying machines and laser-beam printers. The next generation of research in this field was on metallic behaviors of ion-radical salts of tetracyanoquinodimethane (TCNQ), which also encouraged the development of new electronic components. The basic concept of "enhanced electrical conductivity by the aid of the charge-transfer interaction (or electronic doping)" was further applied to organic polymers and carbonaceous materials including graphite. This instigated extensive and interdisciplinary research worldwide and resulted in novel 'synthetic metals.' This research was rewarded with good fruits of solid electrolytic components like 'lithium-ion batteries' and 'specialty-polymer capacitors' which are now vital to almost all digital electronic devices. High-quality graphite which was discovered through industry-academia-government collaboration about 25 years ago has recently found new application as a heat dissipation media in small-size digital devices, thus establishing a large market. |
