New oxygen related shallow thermal donor centres in Czochralski-grown silicon Article uri icon

abstract

  • A series of previously undetected effective-mass like oxygen related donor centres is observed in Czochralski-grown silicon (Czsi) by means of Photothermal Ionization Spectroscopy. The new set of donors is shallower in energy than any of the known series of nine oxygen thermal donors reported in CzSi. The ionization energies of the new set of donors are between 34.7 and 37.4 meV. The new donor centres also appear as a result of thermally annealing the samples at 450°C. © 1986.
