[Research Overview]
The increasing number of electronic devices such as smartphones and personal computers has led to a rise in electricity consumption. Therefore, there is a demand for machines and components that operate with as little power as possible. While miniaturization has been continuously pursued to improve performance, conventional silicon materials are becoming increasingly difficult to miniaturize further, leading to high expectations for two-dimensional materials as alternatives.
Professor Fujimoto is working on applications for semiconductor devices (elements using semiconductor materials) and gas sensors, among others, using the two-dimensional material graphene. In transistors fabricated by combining graphene and molybdenum disulfide, he confirmed that the characteristics can be significantly altered by the combination of materials, providing important hints for the development of high-performance semiconductor devices.
