FIG. 1.

(a) Side view SEM image of the as-grown GaAs NWs. (b) TEM (left) and HRTEM (right) image of a GaAs NW with stacking faults. The arrows indicate ZB segments. Inset: ED pattern shows a mixture of ZB and WZ phases. (c) TEM (left) and HRTEM (right) images of a stacking fault free GaAs NW. Inset: ED pattern shows a pure WZ phase.

spectra from four NWs (labeled 1–4). Note that wires 1 and 2 show emissions at both the WZ and ZB GaAs exciton energies while wires 3 and 4 show only WZ related emissions.

PL spectra of wire 1 measured at different temperatures. All spectra have been normalized for clarity. The dashed curve is to guide the eyes.

FIG. 4.

(a) PL energies of peaks 1 and 2 (as indicated in Fig. 3) as functions of temperature. PL peak energy from a ZB GaAs NW [wire A, Titova et al. Ref. 10] is shown for comparison. (b) as a function of (see text for description).
