Abstract: The results of computer simulation of heat distribution processes taking place after the absorption of single photons of 1 1000 eV energy in the three- layer detection pixel of the thermoelectric detector are being analyzed. Different geometries of the detection pixel with thermoelectric sensor made of strongly correlated semiconductor FeSb2, tungsten absorber and heat sink are considered. It is concluded that such detector may register individual photons from IR to X-ray providing energy resolution of not less than 1 % and terahertz counting rate.


Keywords: Thermoelectric single-photon detector, Computer simulation, Three-layer detection pixel, FeSb2 sensor, Tungsten absorber and heat sink.
