Seminarium Zakładu Mechaniki i Fizyki Płynów Crystal growth under conditions of low melt flow close to interface dr M.A. Gonik, THERMO, Alexandrov, Russia środa, 9 października 2002

New methods of crystal growth from the melt using baffle or AHP heater are discussed. The AHP (Axial Heat flux close to the Phase interface) method is a novel technique for the directional solidification. It has an additional heater submerged in the melting zone. The AHP crystal growth method permits the control of the distribution of the dopant concentration in the melting zone during solidification, the shape of solid/liquid interface and the velocities of the liquid in the melting zone. Therefore it is well suited for studying interface kinetics and simmulating the microgravity conditions.
