THE NON-DETONATIVE SYNTHESIS OF CADMIUM SELENIDE AND OTHER II-VI COMPOUNDS FROM THE ELEMENTS¹

Thermal analyses of compound semiconductors using differential scanning calorimetry. Application to compositional analyses of cathodically electrosynthesized cadmium telluride

“…The melting transitions of Cd and Te are clearly well separated. The transition temperatures of 318 and 447 °C for Cd and Te (with an associated estimation uncertainty of ±1 °C) are in reasonable agreement with previously published (23) DTA values of 321 and 450 °C, respectively. By use of Zn as calibration standard, fusion enthalpies of 59 and 140 J/g were determined for Cd and Te, respectively.…”

“…Reisman has described how DTA could be used to study the thermal synthesis of CdSe and other group 11-VI counterparts from the component elements (23). To our knowledge, the utility of thermal analysis techniques such as DSC for semiconductor compositional analyses has not been previously explored.…”

“…The predecessor of this technique, namely differential thermal analysis (DTA), has also played a pivotal role in the elucidation of phase diagrams (including many involving components of importance to semiconductor technology, cf. Reisman has described how DTA could be used to study the thermal synthesis of CdSe and other group II-VI counterparts from the component elements (23). To our knowledge, the utility of thermal analysis techniques such as DSC for semiconductor compositional analyses has not been previously explored.…”

Fundamentals of the CdTe synthesis

“…The strains can be suddenly released up to the breakage of the tube. Such a situation can be also depicted by the formation of an insoluble passivating layer of CdTe developing around the reactants [2]. This solid layer isolates globules of the liquid metallic element from the remaining bath.…”

A comparative study on CdSe synthesized at low temperature

“…In the case of vapour phase reactions, this is usually rather difficult and from many points of view, impractical. On the other hand, synthesis by reaction of the molten elements may be either too slow for practical purposes (Reisman and Birkenblitt 1963) or too rapid (Korneeva et al 1960), thus causing detonations. To avoid these difficulties, a novel method was adopted for the first time to synthesize CdSe.…”
