Abstract
In situ observations were carried out in faceted transparent organic materials grown unidirectionally by multiwavelength interferometry, which enabled us to measure the distribution of temperature and solute concentration distributions in the liquid in the vicinity of the solid/liquid interface simultaneously. The aim of the experiments was to reveal a mechanism of a faceted cellular array growth taking account of an influence of latent heat of fusion of the material upon a temperature distribution in the melt. Some experimental results were briefly summarized in the present report.
