Research
Shimura Laboratory conducts research on advanced semiconductor materials and devices that support future information and communication technologies and efficient energy use. Building on semiconductor materials and device engineering, the laboratory takes an integrated approach ranging from fundamental studies of material growth and characterization to practical device applications with potential societal impact. This provides a broad learning environment both for students interested in the science of materials and for those who wish to contribute to future technologies and manufacturing.
Our research focuses on three major areas. The first is the development of low-power optoelectronic integrated devices using group-IV semiconductors such as Ge and GeSn. By integrating electronic and photonic functionalities, we aim to enable next-generation technologies including high-speed communications, quantum information processing, biosensing, and high-speed image sensors. The second area is crystal characterization for wide-bandgap semiconductor power devices, particularly those based on SiC. Using advanced techniques such as X-ray topography, we analyze crystal defects in detail and contribute to the realization of high-performance, highly reliable power devices. The third area is the development of thermoelectric devices based on Ge-based materials. We focus on technologies that convert unused heat into electricity and pursue the creation of high-performance materials and innovative device structures for energy-harvesting applications.
Shimura Laboratory offers an intellectually stimulating environment for students who are interested in semiconductors and materials science, wish to learn across a broad spectrum from fundamentals to applications, and aspire to contribute to society through advanced technologies.
