Abstract
Semiconductor materials such as silicon particles are doped by mixing the semiconductor material with a solution having a dopan and a solvent. The solvent is removed from the wetted surface of the particles of the semiconductor material, thereby yielding particles that are substantially free from the solvent and are uniformly coated with the dopant.
