A lab where students create, with their own hands, semiconductor devices that do not yet exist in the world.
AboutAbout the lab
Creating, with your own hands, semiconductors that do not yet exist
The Nishinaga Lab aims to create, with its own hands, semiconductor devices that do not yet exist in the world.
Using compound semiconductors, the lab studies properties such as light emission and high-frequency operation that cannot be achieved with the silicon semiconductors used in smartphones and other devices.
The lab synthesizes compound semiconductors in-house, evaluates their crystalline, electrical, and optical properties, and creates new semiconductor devices.
The lab aims to propose, and put into practical use in society, sensors, light sources, and energy devices that can be used in diverse environments, including in the life sciences.
Key terms
- Compound semiconductor
- A semiconductor material made of two or more elements, with properties that silicon lacks, such as light emission and high-frequency operation
- Solar cell
- A device that converts sunlight into electricity
- Radiation tolerance
- The property of resisting damage and maintaining performance even when exposed to radiation

ResearchResearch themes
The lab synthesizes and studies compound semiconductors in-house, which have properties such as light emission and high-frequency operation that silicon cannot offer. By evaluating their crystalline, electrical, and optical properties, the lab aims to create new semiconductor devices.
*Illustrative imageFabrication of compound semiconductor devices
The lab itself deposits thin films of GaAs, a group III-V semiconductor, and Cu(In,Ga)Se2 (CIGS), a group I-III-VI semiconductor, builds solar cells and photodetectors from them, and evaluates their electrical and crystallographic properties.
*Illustrative imageComputational analysis of device characteristics
Using computational science methods, the lab examines combinations of materials suited to high-efficiency solar cells. It also studies the effects of radiation on semiconductor devices, which feeds into research on highly radiation-tolerant semiconductors for use in space and at nuclear power plants.
