AB  - In the present work, the energy spectra of protons channeled along the (0 0 0 1) axis of SiC polytype crystals (namely 4H and 6H) in the energy range E-P = 400-650 keV, in the backscattering geometry, were taken and analyzed. Computer simulations are in very good agreement with the measured spectra. The accurate reproduction of the experimental channeling spectra in the backscattering geometry is strongly based on the investigation of the correct dechanneling function and a, the ratio of the stopping powers in the aligned and random mode. In the present work, the applicability of a Gompertz type sigmoidal dechanneling function, with two parameters, k and x(c), which represent characteristic dechanneling rate and range, respectively, is examined, and the results are compared to the ones obtained in the past, concerning the same polytype structures, based on the assumption that the dechanneling of protons follows an exponential law, for the energy range E-P = 1.7-2.4 MeV.

AB  - In the present work; the dechanneling of protons in Si [110] is studied combining theoretical Monte-Carlo and phenomenological simulation results in the energy range E-p = 1.8-2.4 MeV. The applicability of a Gompertz type sigmoidal dechanneling function, with two parameters, k and x(c), which represent characteristic dechanneling rate and range, respectively, is examined; yielding the successful reproduction of backscattering spectra of channeled protons along the Si [110] crystal axis. The results are compared to the ones obtained in the past for different beam - crystal orientation combinations and an attempt is made to explain the occurring similarities and discrepancies.
