Abstract:

Ruby monocrystals were produced by vapor phase growth using chromium organometallic compounds as the chromium dopant ion source. The low decomposition temperature of these compounds prevented high dopant homogeneity and sufficiently long growth runs to be successfully conducted. Growth furnace modifications were made which should enable three inch long by 38 - 12 inch diameter crystals to be grown having their longitudinal axes perpendicular to the impinging reactant gas stream. Other modifications were incorporated into the growth system which should enable continuous runs up to 100 hours duration, elimination of some of the problems of non-uniform dopant homogeneity and secondary nucleation, and further improve crystalline purity.
