A paper entitled “Ultra-Sensitive Short-Wave Infrared Single-Photon Detection Using a Silicon Single-Electron Transistor” has just been published in Advanced Electronic Materials (Wiley). This paper shows how a nanoscale silicon transistor, operated in the single-electron tunneling mode, can be a highly sensitive detector of individual photons, in a wide range of wavelengths including infrared.

This work was carried out by Pooja Sudha of IIT Roorkee, visiting our lab for just a few months, in cooperation with our student Shogo Miyagawa and with a long analysis supported by Assoc. Prof. Arup Samanta at IIT Roorkee. Many thanks also to Shizuoka University and funding agencies for supporting this line of research.
Congratulations to all! Let’s look forward to the future developments from such a fundamental demonstration!
