Binding energies of the biexciton confined in the InAs NR with radius as a function of the NR length.
Photoluminescence spectra of InAs NRs of radius at temperatures (a) and (b) . The solid curves corresponds to rod length and the dotted curve corresponds to rod length . The symbol represents the exciton and represents the biexciton.
Photoluminescence spectra of InAs nanorods of radius and length at temperatures of (dotted) and (solid). The symbol represents the exciton and represents the biexciton.
energy separation, between the peak positions of the excitonic and biexcitonic emissions in the InAs NR as a function of the NR length for radius at temperatures of (plot a), (plot b), and (plot c). In all cases the NR radius is .
