$B!!(BIn the 21'st century, opto-electronic conversion elements such as solar cells, opto and electronic  devices such as semiconductor lasers and ULSI, biological macromolecules such as protein would be the essential materials to solve the serious problems: ex. energy crisis, environmental pollution and advanced industrial foundation. All of these materials are essentially based on crystals and the development of the novel functional crystals has the key to solve the problems. The aim of our group is to develop novel crystal growth techniques and new functional crystals on the basis of the crystal growth physics from semiconductor to organic materials. The crystal growth mechanism is investigated from both experimental and theoretical viewpoints. 

$B!!(BNow, we are focusing on the following subjects:

(1) Studies on the materials for solar cells 

(2) Growth of multi-component bulk substrate crystals and studies on hetero-epitaxial structure with controlled stress

(3) Studies on the mechanism of crystal growth

(4) Study on the crystal growth of organic materials
