AboutAbout the lab
Mastering light and electrons to realize a future AI society
The Fujioka Lab uses chemical methods to research new electronic devices that society will need in the future.
In a society where artificial intelligence is widespread, components with unprecedented levels of performance will be needed, such as devices that can communicate large amounts of data at high speed.
Developing such devices requires knowledge of chemistry, including new materials and new fabrication methods.
The lab works on technology for growing semiconductor crystals at low temperatures and on the development of micro-LED displays.
Key terms
- Semiconductor
- A material whose electrical conductivity lies between that of metals, which conduct electricity well, and insulators, which do not. It is used as a material for electronic components.
- Micro-LED
- A display technology in which very small LEDs (light-emitting diodes) are arranged to serve as the individual dots (pixels) of the screen.
- High Electron Mobility Transistor
- A transistor that uses a layer in which electrons move very easily, allowing it to operate at high speed.
ResearchResearch themes
Using chemical methods, the lab aims to develop devices with new functions that will be needed in an AI society. Its research covers technology for growing semiconductor crystals at low temperatures, as well as the development of displays and transistors.
*Illustrative imageGrowing Crystals at Low Temperatures
Semiconductor crystals are usually grown at very high temperatures. By growing them at low temperatures instead, the lab aims to create new electronics that were not possible before.
*Illustrative imageFlexible Devices
The lab is developing flexible devices as a project.
*Illustrative imageMicro-LED Displays
The lab is developing micro-LED displays, which are expected to be a next-generation display technology.
*Illustrative imageHigh Electron Mobility Transistors
The lab is working on the development of high electron mobility transistors (HEMTs).
