摘要:
A method for determining the substitutional carbon content (Cs) of a monocrystalline or polycrystalline silicon sample comprises measuring an absorption spectrum of the silicon sample to be studied and of a reference sample and calculatng a differential spectrum from them, wherein the calculated differential spectrum provides a detection threshold of
