Room temperature polariton lasing in radial quantum well nanowires

Abstract: Semiconductor nanowires are promising building blocks for coherent light-emitters at the nanoscale, which can be exploited in the fields of nanophotonics, nano-optics and nanobiotechnology. Individual nanowires could serve as an optical waveguide along the axial direction and the high […]
