Abstract
All processes occurring in semiconductor detectors during the detection of primary monoenergetic particles lead to spectral line broadening. In this work, a general expression for the energy resolution of semiconductor detectors with several signal electrodes has been obtained using the theory of branching cascade processes. It is shown that the general formula includes all contributions to spectral line broadening described in the literature, as well as additional contributions associated with fluctuations in the lifetimes of electrons and holes due to the inhomogeneous density of traps in a semiconductor material, and fluctuations in the gain of the electronic path. In particular, an approximation for the energy resolution of a semiconductor detector when detecting low-energy X-ray radiation has been derived from the general formula.
