Abstract

In recent years, a series of investigations has been devoted to a possibility of using crystals based on CdTe with addition of magnesium (Mg) for X and gamma radiation detectors. Since we have had wide technological possibilities of preparing crystals and investigating their properties, we performed crystallizations of the crystals mentioned above. Thereafter, we investigated selected properties of the obtained materials. The crystallization processes were performed by using the Low Pressure Bridgman (LPB) method. The elements used: Cd, Te, Mg were of the highest purity available at present. In order to obtain reliable conclusions the crystallization processes were carried out at identical technological conditions. The details of our technological method and the results of the investigation of physical properties of the samples are presented below.
