Noritaka Usami mainly focuses on Optoelectronics, Molecular beam epitaxy, Condensed matter physics, Photoluminescence and Silicon. His Optoelectronics study frequently links to adjacent areas such as Epitaxy. His study in Molecular beam epitaxy is interdisciplinary in nature, drawing from both Quantum wire and Photoconductivity.

The various areas that Noritaka Usami examines in his Condensed matter physics study include Crystallography, Activation energy and Grain boundary. His Photoluminescence study integrates concerns from other disciplines, such as Metalorganic vapour phase epitaxy, Chemical vapor deposition, Exciton, Quantum well and Germanium. His work deals with themes such as Growth rate, Optics, Supercooling, Heterojunction and Grain growth, which intersect with Silicon.

His most cited work include:

  • A quantum-dot spin qubit with coherence limited by charge noise and fidelity higher than 99.9. (368 citations)
  • A >99.9%-fidelity quantum-dot spin qubit with coherence limited by charge noise (313 citations)
  • Optical properties of ZnO rods formed by metalorganic chemical vapor deposition (288 citations)
