Abstract: "Room-temperature
ultraviolet lasing in semiconductor nanowire arrays has been demonstrated. The
self-organized,<0001>oriented zinc oxide nanowires grown on sapphire
substrates were synthesized with a simple vapor transport and condensation
process. These wide band-gap semiconductor nanowires form natural laser
cavities with diameters varying from 20 to 150 nanometers and lengths up to 10
micrometers. Under optical excitation, surface-emitting lasing action was
observed at 385 nanometers, with an emission linewidth less than 0.3
nanometer. The chemical flexibility and the one-dimensionality of the
nanowires make them ideal miniaturized laser light sources. These
short-wavelength nanolasers could have myriad applications, including optical
computing, information storage, and microanalysis."
