Phase Transformation Study of Cu2S.

Abstract:

The phase transformations of crystalline Cu2S in the temperature range 50 C to 600 C have been studied through electric quadrupole interactions studied through electric quadrupole interactions of 111Cd impurities observed by time-differential perturbed angular correlations. The Cd is subject to no discernable quadrupolar interaction in the cubic phase above 430 C. In the hexagonal phase between approximately 103 C and 430 C, a single-site, weakly temperature dependent, axially symmetric quadrupolar interaction is found. At lower temperature, the structure is complex with a number of different sites. These data were taken with a microcomputer-controlled TDPAC spectrometer with logical steering that allows a standard 4-detector spectrometer to collect simultaneously 12 channels of data. Author
