Paper Abstract

We evaluate the prospects of cerium hexaboride (CeB6) crystals for use as a sensitive element in so-called QVD thermoelectric single photon detectors, which operate at cryogenic temperatures. By gathering and analyzing the values of the thermoelectric parameters for CeB6 reported in the literature up to this date, we have evaluated the promise of cerium hexaborides as a sensitive element in thermoelectric single photon detectors at temperatures above 4K. We have concluded that such detectors can detect a single UV photon, have very fast count rate (up to 100 MHz) and a spectral resolution of 12.7 eV. QVD detectors based on CeB6 crystals, by virtue of operating at temperatures above 4 K, can have a wider field of application.
