The energy spectra of the gamma rays emitted by 241Am, 133Ba, and 137Cs were measured using an InSb detector made from a liquid-phase epitaxially (LPE) grown crystal. To understand the relationship between the maximum channel numbers of energy spectra and the maximum energies of gamma rays, a charge collection process is discussed. We performed numerical simulations of the charge collection process with a modified Hecht's equation. We showed that the entire LPE-InSb crystal including outside the depletion layer worked as a sensitive volume.
