We report the use of a valved cracker cell for sulphur in the growth of doped and undoped ZnSSe and ZnMgSSe lattice matched to GaAs for use in multilayer device structures. The cell provides fast flux changes allowing adjacent layers with differing S contents to be produced with a single S source without interruptions in the growth. Material grown using elemental sulphur shows good morphology with both high-quality photoluminescence spectra and X-ray double-crystal rocking curves. © 1998 Elsevier Science B.V.
