Nature of excitons bound to inversion domain boundaries: Origin of the 3.45-eV luminescence lines in spontaneously formed GaN nanowires on Si(111)
Carsten Pfüller, Pierre Corfdir, Christian Hauswald +9
We investigate the 3.45-eV luminescence band of spontaneously formed GaN nanowires on Si(111) by photoluminescence and cathodoluminescence spectroscopy. This band is found to be pa…
Quenching of the luminescence intensity of GaN nanowires under electron beam exposure: Impact of C adsorption on the exciton lifetime
Jonas Lähnemann, Timur Flissikowski, Martin Wölz +4
Electron irradiation of GaN nanowires in a scanning electron microscope strongly reduces their luminous efficiency as shown by cathodoluminescence imaging and spectroscopy. We demo…
Individual electron and hole localization in submonolayer InN quantum sheets embedded in GaN
Felix Feix, Timur Flissikowski, Caroline Chèze +3
We investigate sub-monolayer InN quantum sheets embedded in GaN(0001) by temperature-dependent photoluminescence spectroscopy under both continuous-wave and pulsed excitation. Both…
Crystal-phase quantum dots in GaN quantum wires
P. Corfdir, C. Hauswald, O. Marquardt +6
We study the nature of excitons bound to I1 basal plane stacking faults in ensembles of ultrathin GaN nanowires by continuous-wave and time-resolved photoluminescence spectroscopy.…
