Fine Structure Due to Donor-Acceptor Pair Luminescence in Compensated Si

Tajima, Michio; Iwai, Takaaki; Toyota, Hiroyuki; Binetti, Simona; MacDonald, Daniel


A fine structure on the higher energy side of donor-acceptor (DA) pair luminescence at 4.2K has been analyzed in compensated Si involving P donors and B acceptors. We calculated the density distribution of DA pairs against photon energy from the number of pairs as a function of the transition energy of respective pairs. A close agreement was obtained between the density curve and the observed spectral structure using the generally accepted values of energy gap and P donor and B acceptor...[Show more]
