Existence and static stability of a capillary free surface appearing in a dewetted Bridgman process. Part I.
Journal Title: INCAS BULLETIN - Year 2019, Vol 11, Issue 3
Abstract
This paper presents six theoretical results concerning the existence and static stability of a capillary free surface appearing in a dewetted Bridgman crystal growth technique. The results are obtained in an axis-symmetric 2D model for semiconductors for which ππ+πΌπ<ππ (where:ππ- wetting angle and πΌπ- growth angle). Numerical results are presented in case of InSb semiconductor growth. The reported results can help, the practical crystal growers, in better understanding the dependence of the free surface shape and size on the pressure difference across the free surface and prepare the appropriate seed size, and thermal conditions before seeding the growth process.
