Traveling heater method (THM) experiments on InP crystal growth from indium
solution (SKAT-FD) were performed during the Russian FOTON-11 mission in O
ctober 1997. The aim of these experiments was to ascertain the effectivenes
s of controlling heat and mass transfer in the liquid phase by applying a r
otating magnetic field (RMF). As an effort to understand the parameters inf
luencing the crystal growth a mathematical model was developed for numerica
l simulation of these experiments. The SKAT-FD crystals were grown with RMF
at an induction of 1 and 2 mT. As the calculations show, such magnetic fie
lds influence remarkably the hydrodynamics of the melt, and consequently, t
he growth process. The change of the magnetic induction value (or switching
off the RMF) led to an abrupt change of the growth rate, measured from art
ificial dopant striations produced in the growing crystals by the heat-puls
e technique. (C) 2001 Elsevier Science Ltd. All rights reserved.
