Abstract

The segregation behaviour of a number of important elements in CdxHg1-xTe (CMT) has been established in crystals grown under conditions of accelerated crucible rotation (ACRT). Chemical analysis by atomic absorption spectrometry (AAS), laser scan mass spectrometry (LSMS) and spark source mass spectrometry (SSMS) has been carried out on both deliberately doped and undoped crystals. Estimates of segregation coefficients have been obtained and these are compared to those found in normal Bridgman grown crystals. In general the segregation coefficients are found to be lower in ACRT material and possible causes for this are suggested.
