Process for producing optoelectric articles

摘要

A process for producing optoelectric articles, in which an optoelectric single crystal film is formed on an optoelectric single crystal substrate, is disclosed. The optoelectric single crystal substrate is exposed to a liquid phase in a supercooling state of a melt including a solute and a melting medium, and the optoelectric single crystal film is formed by a liquid phase epitaxial process. In this case, a viscosity of the liquid phase is set to 75% DIFFERENCE 95% preferably 75% DIFFERENCE 90% with respect to a viscosity at which a degree of supercooling of the liquid phase is zero.
