Identification and control of a multizone crystal growth furnace

Automation of Crystal Growth from Melt

“…The model-based temperature control of the Bridgman processes has been the subject of several publications by Batur et al In Refs [132,152] a method for the identification of a linear lumped parameter MIMO model of the heating zone system is proposed. The model is used for the design of a self-tuning linear state space controller for tracking of the zone temperatures.…”

In-situ temperature field measurements and direct observation of crystal/melt at vertical Bridgman growth of lead chloride under stationary and dynamic arrangement

“…Image processing inside a transparent vertical Bridgman furnace during growth of lead bromide was performed by Batur et al [8]. Direct observation of the crystal/melt interface to study the three-dimensional characteristics of interfacial instabilities was described by Singh et al [4].…”
