Transient decay of satellite lines of bound excitons in Si: P

Abstract

The transient decay of the α and β series of lines in the photoluminescence spectrum of Si: P are reported. The decays of the α lines are compared with the decays of the β lines. The results are consistent with β_2 having the same initial state as α3. The results for β_1 and β_3 are less certain. Their decays are consistent with β_1 having the same initial state as either α_2 or α_3, and with β3 having the same initial states as α_4. Overlap between lines, uncertainty in the decay of the boron bound exciton and the presence of unidentified background all make it difficult to make conclusive line assignments.
