Growth of Large Cd3As2 Single Crystals Using the Vertical Version of the Chemical Transport Reaction Method

Needle-like, plate-like, and bulk Cd3As2 crystals with record values of weight and sizes have been grown by the chemical transport reaction method using vertical mass transfer. The mass transfer and growth rate were calculated based on the data on the partial vapor pressures of Cd and As4 in order to optimize the growth conditions. Identification and monitoring of the structural quality of crystals were performed using a complex of methods of physicochemical analysis, including X-ray phase analysis, as well as atomic-force, optical, and electron microscopy.
