Kinetics of the vapour-phase growth of II–VI compounds in a sealed tube
TL;DR: In this article, a theoretical study of the vapour-phase growth of II-VI compounds in sealed tubes (Piper-Polich method) has been made by considering the whole growth process in three main steps: vaporization of the charge, transport of vaporized components and crystallisation from the vapours.
Journal ArticleDOI
Supersaturation control in crystal growth of II–VI compounds from the vapour
P.A. Tempest,D.W.G. Ballentyne +1 more
TL;DR: In this article, a theoretical approach to the diffusion of the vapours and their condensation at the crystal surface is presented, showing that the supersaturation is a function of the transport resistance and the surface resistance.
Journal ArticleDOI
The growth of single crystals of electro-optic organic compounds in monomode optical fibres
D.W.G. Ballentyne,S.M. Al-Shukri +1 more
TL;DR: In this paper, a lower bound for the diameter of a capillary tube is established for the growth of good single crystals by the usual Stockbarger method, if there is an adequate supply of the molten material, there is no fundamental reason why infinitely long organic single crystal should not be grown by the inverted technique.
Journal ArticleDOI
The growth of cadmium sulphide from the vapour phase — Optimum growth conditions
TL;DR: In this paper, the growth of cadmium sulphide from the vapour phase is described in mathematical terms, using an atomistic model for the solid/vapour interfaces as the basis of the boundary conditions used to solve the transport equations.
Journal ArticleDOI
The growth of cadmium sulphide from the vapour phase-surface kinetics
D.W.G. Ballentyne,L.M. Rouse +1 more
TL;DR: In this article, a model for the growth of cadmium sulphide crystals on the (11.2) face is proposed, and data on equilibrium partial pressures versus temperature are used to compute values of atomic binding energy and vibration frequency which are model dependent.
