The Calculation of Some Gamma Shielding Parameters for Semiconductor Cspbbr3

Abstract

Recently, researchers produced perovskites structures used in optoelectronic devices as substrates, sensors. CsPbBr3 crystal is found in the cubic perovskite structure and its space group is Pm-3m. CsPbBr3 is a developing material for detection of X- and gamma-ray radiations and the knowledge of the attenuation parameters of CsPbBr3 crystal is important. In this study, some photon shielding parameters such as mass attenuation coefficient (mu(p)), effective atomic number (Z(eff)), and electron density (N-el) have been investigated for CsPbBr3 compound. The theoretical values of mu(p) have been calculated in the energy range from 1 keV to 100 GeV using WinXCom computer code and these values have been used in order to calculate the values of Z(eff) and N-el in the same energy range.
