Abstract
A method for doping crystals is disclosed. The method includes a receiver for receiving semiconductor spheres and a dopant. The semiconductor spheres are heated to a molten state. The dopant is absorbed by the semiconductor spheres. The semiconductor spheres are cooled to produce doped semiconductor spheres. The method is performed in a non-contact environment.
