A lab that explores solar cells and optical devices using quantum dots and III-V semiconductors.

The Miyashita Lab, jointly with the Yamaguchi Lab, conducts basic research on creating nanometer-sized materials and investigating their properties. The central focus is quantum dot structures that confine electrons and holes in three dimensions, and the lab also works with quantum nanowires (quantum wires). The Miyashita Lab also develops technologies for solar cells, such as multijunction solar cells combining III-V semiconductors, and studies methods for evaluating them. The lab's website is shared with the Yamaguchi Lab and the Kaizu Lab, and they are introduced together on the same site.

A lab that uses tiny superconducting devices to trace the sources of nonequilibrium quasiparticles.

The lab studies devices built from tiny junctions, such as Josephson junctions and single-electron devices. It has developed a highly sensitive method for detecting phonons using a single Cooper-pair transistor. Using this detection method as its main tool, the lab tackles the problem of where nonequilibrium quasiparticles in superconducting electrodes come from, which is one of the major causes of decoherence in superconducting qubits.

The lab explores the birth of stars with radio telescopes and develops its own receivers.

The Sakai Lab develops receivers for radio telescopes and uses them in observations to study how stars are born. In particular, the lab aims to clarify how massive stars, which have at least eight times the mass of the Sun, are formed. The lab not only observes with existing instruments but also mounts instruments it has developed itself on large radio telescopes for observation. Star-forming sites are cold and cannot be seen in visible light, so the lab studies them by observing radio waves.
