Education and Research Activities in the Laboratory
Many daily necessities around us, such as TVs, computers, and mobile phones, are composed of silicon-based semiconductor devices. The Information Device Science Laboratory conducts research on information function devices that will support the next-generation information society. Key features of our research include the introduction of various new materials on silicon substrates, our own unique designs, and production of semiconductor devices that make the most effective use of their characteristics. Thus, we are working on producing semiconductor devices with innovative functions on the basis of skilled manufacturing.
1. Next-generation high-tech information terminals
2. LSIs with new functions based on biological supramolecules
3. Printed/flexible displays using wide band gap materials
4. Printing technology for energy harvesting devices (solar cell, thermoelectric devices)
5. Emerging devices (Graphene transistors, power devices based on GaN)
