PHASE STUDIES OF THE CD-FE-SE SYSTEM IN THE CD-RICH REGION

The cadmium-rich region of the semi-magnetic semiconductor Cd-Fe-Se ph ase diagram has been partially determined, for the first time, by x-ra y diffraction techniques and by metallurgical microscopy. The maximum solid solubility of iron in CdSe, employing annealing techniques, has been found in this work to be about 19 at. % at 925-degrees-C, while t he solid solubility limit is generally discussed to be about 12 at. %. The CdFeSe system appears to be a pseudo-binary one. Further consider ations about the structure of this system are discussed.
