Oiwa Laboratory

About us

We study novel optical, electronic, and spin devices that support the highly-sophisticated information society in the 21st century. Based on semiconductor devices, our research fields are quantum information processing using the quantum mechanical nature of electron spins and photons, and spintronics based on the development and hybridization of optical, electrical and spin materials. We study the growth and characterization of high quality materials and perform precise quantum transport measurements. Aim of our research is the realization of novel phenomena emerging in quantum nano-structures that can control the photon, electron and spin degrees of freedom.
