Paper
An automated system for the growth of multilayered structures in the (GaAl)As system by LPE
Abstract
Both the apparatus and procedures which we use for growing double heterostructure lasers by LPE have been improved with regard to their reproducibility, ease of operation and efficiency. The major part of these improvements has been in designing a system by means of which growth crucible may be manipulated in the furnace using a stepping motor. By using this facility it has been possible to automate the growth process. As a result of these changes both the yield of high quality crystals and the efficiency of their production have greatly increased. © 1979.
