Abstract
The complete pseudobinary HgTe-CdTe constitutional phase diagram was determined by precision differential-thermal-analysis measurements and used to calculate the segregation coefficient of Cd as a function of Cd concentration and interface temperature. A thorough error analysis was made, and the results are compared with published data. Empirical, analytical-expressions were developed for the liquidus and solidus compositions as functions of temperature to facilitate calculations of phase equilibrium parameters.
