Photoluminescence characterization with a surface treatment suggests that a reduction in the radiative recombination rate of GaAs nanowhiskers is caused by charge separation in depletion potential. Good agreement is obtained between photoluminescence characteristics and calculations based on self-consistent wavefunctions confined in the depletion potential. The radiative life time of 200-nm GaAs nanowhiskers at 77 K is estimated as short as 0.5 ns if the depletion potential is completely eliminated. Weak size dependence of photoluminescence spectra at 6 K is explained as a sign of band-gap reduction induced by the depletion potential.
