The lab creates environmentally friendly semiconductors, starting from the technology of growing crystals.
AboutAbout the lab
Growing crystals for energy-saving semiconductors.
The Deura Lab studies "environmental semiconductors" that contribute to energy saving and energy generation.
While taking a comprehensive view of materials, devices, and systems, the lab focuses on crystal growth to control the properties of environmental semiconductors as desired.
Building on semiconductor crystal engineering and crystal growth technology, the lab advances its research by integrating with a variety of fields.
Key terms
- Environmental semiconductors
- Semiconductor materials that help save energy and generate power, and contribute to carbon neutrality
- Crystal growth
- The process of arranging atoms in a regular pattern to grow a crystal with the desired properties
- Thermoelectric conversion
- A mechanism that extracts electricity from a temperature difference, or creates a temperature difference using electricity

ResearchResearch themes
The Deura Lab takes a comprehensive view of the materials, devices, and systems of environmentally friendly semiconductors, or "environmental semiconductors." In particular, it focuses on establishing the scientific principles of crystal growth and developing the technology for controlling material properties.
*Illustrative imageConverting heat into electricity with nitride semiconductors
The lab clarifies the thermoelectric properties of nitride semiconductors, builds thermoelectric devices, and evaluates their performance. The aim is a system that makes effective use of waste heat from optical and electronic devices.
*Illustrative imageCarbonizing the surface of silicon
When a silicon substrate is heated while a carbon source is supplied, the surface is carbonized and forms a thin film of silicon carbide. The lab is clarifying the mechanism of this carbonization and demonstrating it through crystal growth on the resulting substrate.
*Illustrative imageCombining diamond and nitrides
The lab aims to realize new devices by combining the respective advantages of diamond and nitride semiconductors.
