Simulations and Design of a Single-Photon CMOS Imaging Pixel Using Multiple Non-Destructive Signal Sampling
Konstantin D. Stefanov, Martin Prest, Mark Downing +3
A single-photon CMOS image sensor design based on pinned photodiode (PPD) with multiple charge transfers and sampling is described. In the proposed pixel architecture, the photogen…
Optical Response of Strained- and Unstrained-Silicon Cold-Electron Bolometers
T. L. R. Brien, P. A. R. Ade, P. S. Barry +10
We describe the optical characterisation of two silicon cold-electron bolometers each consisting of a small () island of degenerately doped silicon with s…
A Strained Silicon Cold Electron Bolometer using Schottky Contacts
T. L. R. Brien, P. A. R. Ade, P. S. Barry +10
We describe optical characterisation of a Strained Silicon Cold Electron Bolometer (CEB), operating on a stage, designed for absorption of millimetre-wave radiati…
Superconducting platinum silicide for electron cooling in silicon
M J Prest, J S Richardson-Bullock, Q T Zhao +7
We demonstrate electron cooling in silicon using platinum silicide as a superconductor contact to selectively remove the highest energy electrons. The superconducting critical temp…
Strain enhanced electron cooling in a degenerately doped semiconductor
M. J. Prest, J. T. Muhonen, M. Prunnila +9
Enhanced electron cooling is demonstrated in a strained-silicon/superconductor tunnel junction refrigerator of volume 40 um^3. The electron temperature is reduced from 300 mK to 17…
Strain control of electron-phonon energy loss rate in many-valley semiconductors
J. T. Muhonen, M. J. Prest, M. Prunnila +8
We demonstrate significant modification of the electron-phonon energy loss rate in a many-valley semiconductor system due to lattice mismatch induced strain. We show that the therm…
