Essay

The method of differential thermal analysis studied changes in the melting point alloys CdTe-Al in the concentration range of 1-10 mоl. % Al and recorded its gradual decline from 1365 to 1268 K with increasing Al content. Speculate about the formation of the second phase of the system, which is based Al2Te3. Using a vertical Bridgman growth method a series of single-crystal CdTe:Al, doped in the 3х1017 - 2х1019 at/cm3 range, were grown. By ICP-MS the distribution of Al along CdTe ingots was studied and the value of effective segregation coefficient (Кeff=0,2-0,24) was estimated.
