Mathematical Modeling of Holding Melting Zone with LF and HF EM Fields in Floating Zone Crystal Growth Facilities


Abstract

A floating zone facility with EM field pressure supported melting zone is proposed for germanium crystal purification. A test facility is planned to be built at the Institute of Atomic Physics and Spectroscopy at University of Latvia. A simplified analysis of generated EM power and heat transfer shows that aluminum is the best material for the test facility. A 2D axisymmetric, quasi-steady state model for the EM field distribution and free surface shape has also been developed, and first simulation results are presented, including some of the working parameters of the proposed test facility.
