インタヴュー記事④
Currently, gallium oxide is attracting attention because of its potential as a material for power devices (semiconductor devices for electric power). Power devices are components that control electrical energy, and the ones currently in widespread use silicon as a material. Silicon carbide (silicon carbide) and gallium nitride have already been commercialized as new semiconductor materials for power devices. However, these materials have the disadvantage of high manufacturing costs.

Power semiconductor materials from Japan
NCT was established in 2015. The founding investors were Tamura Corporation, an electronics parts manufacturer, and domestic researchers who had been studying gallium oxide. The idea of using this material as a semiconductor was conceived by Japanese researchers, and Japan is leading the way in practical applications.
Gallium oxide was originally researched as a substrate for light-emitting diodes (LEDs). In 2008, Tamura Corporation acquired Mitsunami, an optoelectronics company that had been developing gallium oxide LED substrates, and began researching this material. He recalls, "As I was working with the material, I began to think that it might have promising applications as a power semiconductor.
