Numerical simulation of crystal growth in a vertical bridgman furnace

A computational thermal analysis for the zone-refining processes of Cd and Te

“…According to Refs. [24,26], the thermal conductivity of the insulation ceramics should be several times larger than its literature value of 0.13 W/m K, due to the in-homogeneities in the insulator, such as air gaps, channels for optical sensors, thermal couples, power supply, etc. Therefore, we used the value of 1.0 W/m K in the present work.…”

Thermal convection and related instabilities in models of crystal growth from the melt on earth and in microgravity: Past history and current status

“…This configuration was studied as a relevant model of the vertical Bridgman (Crochet et al [34]; Favier [35]) or liquid encapsulated melt zone technique (Lopez et al [36]). The critical parameters corresponding to a transition from the steady axisymmetric (basic state) to the three-dimensional asymmetric (steady or oscillatory) flow pattern were computed and it was elucidated that the instability of the flow is threedimensional for the whole range of governing parameters studied.…”

Numerical modeling and investigation of liquid phase epitaxy of Hg1–xCdxTe infrared detectors

“…Additionally, the convection in the melt, in the porous isolation medium and inhomogeneities caused by power lines, thermocouples for furnace control etc. are neglected for the global simulations as well [11]. As a result of these assumptions, only the energy equation and the StefanBoltzmann's radiation law have to be considered in the global model with a Newton's cooling condition, which are given as follow:…”
