K. Ohdaira et al., Observation of negatively charged excitons and excited states of multi-excitons in quantum dots embedded in modulation doping structures, PHYSICA E, 11(2-3), 2001, pp. 68-71
Existence of negatively charged excitons in quantum dots (QDs) is confirmed
by the measurement of the bias dependence of luminescence from modulation
doped structures with embedded QDs. Excited states of multi-particle states
are also identified from the bias as well as the excitation intensity depe
ndence of micro-photoluminescence peaks. (C) 2001 Elsevier Science B.V. All
