Masaya joined NPL in 2009, after completing a PhD in semiconductor physics at the University of Cambridge in 2000 and postdoctoral positions held at the Cavendish Laboratory in Cambridge. He also had a brief appointment as a guest researcher at the NTT Basic Research Laboratories in Japan in 2006. He is a member of the IOP.
Masaya leads the Single Electron Device team at NPL, and have extensive collaboration with other NMIs, universities, and other research institutes. He is also the Coordinator of the European Metrology Programme for Innovation and Research and Innovation project e-SI-Amp, a collaboration of 10 NMIs and academic institutes developing single-electron primary ampere standards and small-current measurement technique. He has published over 60 publications.
Masaya’s main research interest is in the development of semiconductor single-electron devices. He has expertise in cleanroom III-V semiconductor device fabrication and cryogenic electrical measurements. He has extensive experience in experimental work on quantum Hall effect, Coulomb blockade effect, Aharonov-Bohm interferometry, surface acoustic waves, and single-electron transport.
He is currently leading NPL’s research effort towards the most accurate SI ampere standards based on single-electron devices that will support the future primary electrical metrology. Masaya is also developing experimental techniques for electron quantum optics, technologies that will enable ultrafast electronics and quantum-enhanced sensing beyond the capabilities of current electronic devices.
