Our laboratory, founded in 2003 as the crystal chemistry research laboratory of IMR, was based on the recognition that the development of almost every functional material and device in the area of information technology has been aided by the improvement of the associated single crystals. Our lab has been concerned with novel growth methods, mainly from a melt or a solution, focusing on the role of the local equilibrium and growth dynamics at the interface. The principle underlying our research is the use of the ‘freedom’ present at the interface. An increase in freedom allows a more variable growth process, while a decrease in freedom confines the growth conditions necessary to obtain a homogeneous crystal. Research areas associated with this principle are: (1) Growth under an applied electric field, (2) Growth of a new ferroelectric crystal that is both stoichiometric and congruent, and (3) Phase transition studies at a microscopic scale via colloidal crystallization.
