Experimental conditions were investigated for growth of inclusion-free near-stoichiometric CdZnTe single crystals with a minimized concentration of native point defects. The positions of the stoichiometric line PS = 8×105exp (-1.76×104/T) (atm) and the room-temperature and high-temperature p-n lines were evaluated from high-temperature in situ [...]
