Dan`ko, A.Ya.; Nizhankovsky, S.V.; Kanischev, V.N.; Sidelnikova, N.S.; Adonkin, G.T.; Puzikov, V.M.; Grin, L.A. (Functional Materials, 2006)

The gas environment process formation in the furnace for sapphire growth by horizontal directional crystalliztion equipped by a graphite heating assembly has been studied during the evacuation and the inert gas (Ar, He) ...
Monitoring system of the front of the melt crystallization

Adonkin, G.T.; Barannik, S.V.; Kahishchev, V.N.; Sobolev, O.V.; Voinov, A.I. (Functional Materials, 2012)

A system for automatic determination of the position of the crystallization front in the process of growing sapphire crystals by horizontal directed crystallization (HDC) has been developed. The images of the crystallization ...
Optical properties and fine faulty structure of sapphire crystals grown in low pressure CO gas atmosphere

Puzikov, V.M.; Danko, A.Ya.; Adonkin, G.T.; Sidelnikova, N.S.; Tkachenko, V.F.; Budnikov, A.T. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2000)

Presented in this paper are the results of the study of optical characteristics and fine faulty structure of big sapphire crystals grown in a CO-based low pressure (0.1...0.3 torr) gas atmosphere. Optimal conditions for ...
Optimization of temperature conditions for the growth of large-size sapphire crystals by the method of horizontally directed crystallization

Grin, L.A.; Budnikov, A.T.; Sidelnikova, N.S.; Adonkin, G.T.; Baranov, V.V. (Functional Materials, 2013)

The coefficient of dislocation gliding over the planes of easy glide depending on the shape of the crystallization front, is determined. The regions of non-uniform distribution of thermal field in the crystal are established. ...
