Crystallization of Amorphous Selenium Films Prepared by Vacuum-Evaporation

概要

An electron microscopic study was made on the crystallization of amorphous selenium films prepared by vacuum-evaporation onto glass at room temperature. The films were crystallized by irradiation of an electron beam, and changed into metallic selenium. The crystals grew most prominently in their a-axes with the (011^^-0) surface planes. Small-angle-tilt and twist boundaries as well as twinning crystals were observed in the growing crystals. The generation of the twist boundaries and the twinning crystals are interpreted by mechanisms similar to those proposed in a previous paper (J. Phys. Soc. Japan 21 (1965) 335), and that of tilt boundaries is also interpreted by a modified mechanism.
