The effect of temperature gradient and ampoule velocity on the composition and other properties of Bridgman-grown indium antimonide. Venkataraghavan, R., Rao, K., & Bhat, H. Journal of Crystal Growth, 1998.
abstract   bibtex   
A systematic study of the role of the melt-solid interface position in determining the crystal quality of Bridgman-grown indium antimonide ingots is made. The crystals are grown under various conditions of imposed gradients and velocities. The gradient-to-velocity ratio A in the crystal is seen to move the interface position above or below the melting-point isotherm and this in turn affects crystal quality and grain structure. Post-growth investigations reveal that the growth takes place under off-stoichiometric conditions, for large as well as for small values of Λ, undesirable for growth of high-quality homogeneous ingots of InSb. However, crystals grown under 'near-equilibrium' conditions are stoichiometric, show low defect density, improved grain structure and comparatively narrow rocking-curve width, with very high mobility. © 1998 Elsevier Science B.V.
