We report on the growth of microns long Mn-catalyzed GaAs nanowires. alpha-Mn is found on top of the wires, demonstrating that Mn acts as the growth catalyst. Transport measurements show that the wires have a p-behavior. Luminescence shows a peak at 1.522 eV. The blue shift with respect to bulk GaAs is not due to quantum effects.

Abstract
We report on the growth of microns long Mn-catalyzed GaAs nanowires. alpha-Mn is found on top of the wires, demonstrating that Mn acts as the growth catalyst. Transport measurements show that the wires have a p-behavior. Luminescence shows a peak at 1.522 eV. The blue shift with respect to bulk GaAs is not due to quantum effects.File in questo prodotto:
