Abstract : The invention provides a method for growing a continuous, single crystal filament of a large variety of substances. For systems in which direction v-l-s mechanism is operative, continuous filament growth can be achieved by pulling a filament with a molten solution drop on the end from a heated zone of vaporous reactants. By pulling the filament from the heated zone of vaporous reactants at the speed of filament formation, the molten drop is maintained correctly in the heated zone and the desired temperature gradient is maintained across the molten drop. Continuous single crystal growth results.
