FLOSFIA is a start-up working on a new wide band gap material: Gallium-Oxide. It’s a spin-off from Kyoto University created in 2013. The company develops what they call a “α-type” Gallium-oxide structure. Professor Shizuo Fujita from Kyoto University developed first this new material. It provides a band gap of 5.3eV, much wider than other semiconductor wide band gap material. You can find more information about FLOSFIA in our last news on the subject.
Today Denso, one of the largest automotive equipment suppliers, announced they will invest in FLOSFIA in C series funding. Denso is the main supplier of Toyota. They helped develop the well-know and established hybrid system in Toyota Prius, Camry or other Lexus hybrid cars.
According to Denso, this material can provide better efficiency, cost, size and weight for Electric Vehicle in the future. At the time Silicon Carbide (SiC) and Gallium Nitride (GaN) are finally hitting market with the first wide band gap based converters, Denso is already looking at the next step. It may be found in Gallium Oxide power semiconductors.
