Abstract

We report the cathodoluminescence (CL) study of bound-exciton-polaritons in ZnO whispering gallery (WG) microcavity. Thanks to the very high spatial resolution (: 100 nm) of CL technique, a scanning CL mapping along the tapered ZnO nanowire is achieved. We observe a clear anticrossing behavior which demonstrates the strong coupling between cavity mode and bound-excitons. Coupled oscillator model including both bound excitons and free excitons fits well with the experimental results. The energy splitting of bound-exciton-polaritons:2.6 meV is obtained.

(a) The SEM image of dispersed ZnO tetrapods on Si substrate. (b) The enlarged SEM of a single ZnO tapered nanowire (one arm of tetrapod) extracted from the white rectangle region from (a). (c) The CL spectra measured on the position P1 (middle part of nanowire) and P2 (the root part of nanowire). (d) Cavity mode (WGM) with linewidth:1.6 meV is clearly observed in the spectrum (P1).

The scanning CL mapping along the c-axis of ZnO nanowire, the modulated WG modes (N = 9 −12, yellow stars) can be clearly observed. Excitons-related transitions are also labeled by red lines.

Fig. 3
Fig. 3

(a) The scanning CL mapping along the c-axis of ZnO nanowire at bound-excitons energy region. A log-scale for intensity is used. (b) The expanded view of anticrossing region is shown. The cavity modes peaks are carefully extracted by multi-peaks fitting and second-order differential treatment. The dashed red curves (colored curves in (b)) are calculated by multi-oscillators coupling model with both free and bound excitons included.
