■要約
Fukuyama laboratory studies novel material processing based on chemical thermodynamics with high-temperature thermophysical property measurements. As examples, we are developing new crystal growth processes for nitride-semiconductor devices, which are next-generation optical devices applied in environmental, medical, bio and information technologies fields. Thermophysical properties of materials are needed for modeling heat and mass transports in materials processes. A new thermophysical property measurement system is currently under development, which enables accurate measurements of heat capacity, thermal conductivity, emissivity, density and surface tension of high-temperature melts, utilizing electromagnetic levitation in a dc magnetic field. In addition, we are also fabricating ferromagnetic shape memory alloy and developing microactuators.
