Abstract
Electronic transitions of shallow thermal donors (STDs) in aluminium-d oped Czochralski (CZ) Si annealed at 470 degrees C have different ener gies from those of STDs observed in annealed, hydrogenated boron-doped CZ Si. A third type of STD is observed in boron-doped Si pre-heated i n nitrogen gas and annealed at 550 degrees C. Combinations of the thre e types of STDs can be observed in suitably treated samples. The incor poration of H and Al in STDs has been supported by electron-nuclear do uble-resonance measurements of the Si-NL10 electron paramagnetic reson ance spectrum but the incorporation of nitrogen remains uncertain.
