摘要：

Recombination spectra of excitons and trions in two-dimensional hole gas are studied in two-beam magneto-PL. The singlet, dark-triplet and bright-triplet trions are all identified, and their binding energies are determined. Below the trion energies, the cyclotron replica is identified. Based on the realistic numerical calculation, this peak is attributed to the shake-up process that involves a trion bound to a neutral acceptor located inside the quantum well.
