Sphalerite-type Cd(Te,Se) crystallised by self-selecting vapour growth

Monocrystals of sphalerite-type CdTe1-xSex were grown by self-selecting vap our growth SSVG in the horizontal configuration. As measured on a series of points of a (110) split plane, the "rocking curve" half-width was below 30 arcsec, while the lattice parameter measurements demonstrated the molar fr action x varying within 0.0024 (0.24 %). The values of x obtained from phot oluminescence spectra taken from samples of different quality were in the r anges of 0.0034 (0.34%) and 0.0047 (0.47%). On the basis of the photolumine scence measurements, the maximum difference in x within the crystallised ma terial was estimated to be 0.01 (1%).
