Flux crystal growth technique for next-generation device applications
The flux method is one of the niche sciences for crystal growth. It is a type of liquid-phase growth method and is the most versatile method for growing single crystals. For flux growth, the components of the desired substance are dissolved in the flux, and crystal growth (and crystal layer formation) takes place at a relatively low temperature. One of the important advantages is that crystals can grow free from mechanical or thermal constraints in the solution and the grown crystals have well-developed facets. By combining computational science and the flux method, we are particularly focusing on the development of visible-light-driven photocatalysts, all-solid-state lithium ion batteries and inorganic ion exchangers from the viewpoints of material design, crystal growth and device fabrication.
