Abstract

The physical parameters calculated using Full Potential Linear Muffin Tin Orbitales FP-LMTO method is satisfying. Using the photon mass attenuation coefficient obtained via XCOM data of Cd1-xZnxTe compound, the effective atomic number and the effective electron number were determined in the energy range of 10 to 100 keV. The effective atomic and electron numbers are linearly related and they also depend on the incoming photon energies and weight fractions of elements present in Cd1-xZnxTe. This work aimed at the estimation of the Zeff and the Neff of Cd1-xZnxTe in the energy range of 10 to 100 keV. In the energy range of 40 to 100 keV, the effective atomic and electron numbers were found to be constant. The Zeff and the Neff decrease with the increase of the zinc concentration in the material. The effective atomic number takes values between the lowest Z = 30 of zinc and the highest Z = 52 of tellure in ZnTe and the ternary Cd1-xZnxTe. But for CdTe, it takes values between Z = 42 of cadmium and Z = 52.
