In this paper, the first quanta image sensor with photon counting capability is demonstrated, and the lowvoltage device demonstrates less than 0.3e-r.m.s. read noise on a single read out without the use of avalanche gain and single-electron signal quantization.Abstract:
The first quanta image sensor jot with photon counting capability is demonstrated. The low-voltage device demonstrates less than 0.3e- r.m.s. read noise on a single read out without the use of avalanche gain and single-electron signal quantization is observed. A new method for determining read noise and conversion gain is also introduced.read more

Composition of 1 f Noise in Metal-Insulator-Metal Tunnel Junctions
TL;DR: In this paper, the authors studied the low-frequency conductance fluctuations of very small-area metal-insulator-metal tunnel junctions, and they found that the spectral power density at high temperature is typical of the noise, but is resolved into a small number of Lorentzian spectra for $T\ensuremath{\lesssim}80$ K.
