Abstract

Peculiarities of Cd_0.95-xMn_xZn_0.05Te (x=0.05-0.25) alloys melting and crystallization kinetics were investigated by the differential thermal analysis at various heating/cooling rates. We synthesized Cd_0.95-xMn_xZn_0.05Te alloys from elemental materials in a double-zone furnace. Their melting-crystallization rate was 5- and 10-K/min with a melt-dwell time of 1-, 10-, 20-, and 30-minutes. We found that the melting temperature, T_m, declined with increasing “x”, while the crystallization temperature, T_s, rose with increasing “x”. We detailed the dependencies of the crystallization rate versus the melt’s crystallization temperature. In most cases, the dependencies dropped with the rise of the crystallization temperature, while the crystallization temperature fell with decreasing melt-dwell time.
