Abstract

This chapter reviews studies of amorphous, glassy, and nanostructured Se, focusing on their atomic structures, physical properties, light-induced phenomena, and recent photoconductive applications. Among the group VIb (16) elements, Se forms a monatomic glass having two-fold covalent and van der Waals bonds that possesses a bandgap of \(\approx{}{\mathrm{2}}\,{\mathrm{eV}}\), in contrast to \(\mathrm{SiO_{2}}\), which has three-dimensional networks consisting of fairly ionic Si-O bonds and a wide bandgap (\(\approx{}{\mathrm{10}}\,{\mathrm{eV}}\)). The dualistic bonding structure of Se causes a low glass-transition temperature (\(\approx{}{\mathrm{310}}\,{\mathrm{K}}\)), the narrow gap provides photoconductive responses covering visible wavelengths, and the heavy atomic mass of 79 can afford high x-ray sensitivity. In addition, the one-dimensional atomic structure becomes a framework of needle-like and single-chain nanostructures.

Abe, emeritus professors of Hokkaido University, who introduced him to the physics of polymers and semiconductors.
