(Color online) Typical PL spectra from several single ZB and WZ InP nanowires at .
(Color online) Integrated intensity of PL emission at from single ZB NW A and WZ NW 1 as a function of linear polarization analyzer angle.
(Color online) PL spectra from single ZB NW A and WZ NW 1 as a function of temperature. For comparison, PL spectra from a thick (100)-oriented epilayer is shown at 15 and .
(Color online) (a) Peak position of the emitted PL as a function of temperature for WZ NWs 1 (▴) and 2 (+) and ZB NWs A (●) and B (+). For comparison, the peak position of the emitted PL from a thick (100)-oriented InP epilayer is shown (○). (b) The integrated intensity of WZ NW 1 is plotted as as a function of , where is related to the integrated intensity at zero temperature. The exciton binding energy of is marked by arrow.
