We have used a polarized microluminescence technique to investigate photocarrier charge and spin transport in n-type depleted GaAs nanowires ($ \approx 10^{17}$ cm$^{-3}$ doping level). At 6K, long-distance tail appears the luminescence spatial profile, indicative of transport, only limited by length NW. This is independent on excitation power temperature. Using self-consistent calculation base...
