Synthesis and Structure of Mn-Doped CdGeAs2 Single Crystals

  • 47 Accesses

Abstract

Large, perfect CdGeAs2 single crystals doped with 0.006, 0.49, and 0.89 wt % Mn are grown by the Bridgman method. The Mn concentration in the crystals is determined by atomic absorption spectrophotometry. X-ray diffraction results indicate that Mn doping influences the bond distances in CdGeAs2 and its lattice parameters. Based on the observed structural changes, a model is proposed for the Mn incorporation into the structure of CdGeAs2.
