Abstract
InP crystals were grown by the LEC technique in SiO 2 and BN crucibles using undoped InP polymaterial synthesized in BN boats. Chemical analyses of the Si contamination was made by atomic absorption spectroscopy using a graphite tube system. A comparison of the Si contents of the InP polymaterial, the InP crystals grown in BN and SiO 2 crucibles and the B 2O 3 encapsulant before and after growth led to the following result: LEC growth of InP in SiO 2 crucibles increases the Si content in the crystals due to the reaction between B 2O 3 and the SiO 2 crucible.
