The calculations of the temperature field of the InP growth system are carried out with a stationary FEM/Newton algorithm. With regard to the radiation transparency of the B 2 O 3 layer, the limiting cases transparency and non‐transparency are investigated. With the thermocouples which are inserted into the crystal, the temporal temperature behavior at selected positions of the crystal is recorded. The shapes of the crystal/melt interface of further crystals are analysed by microscopy. Computational and experimental results agree.
