Exciton-related electroluminescence from ZnO nanowire light-emitting diodes. Applied Physics Letters 94(24): 241120.0003-6951http://nrs.harvard.edu/urn-3:HUL.InstRepos:5096631The authors study the microscopic origin of the electroluminescence from zinc oxide (ZnO) nanowire light-emitting diodes (LEDs) fabricated on a heavily doped p-type silicon (p-Si) substrate. By comparing the low-temperature photoluminescence and electroluminescence of a single nanowire LED, bound- and free-exciton related recombination processes, together with their longitudinal-optical phonon replicas, can be identified as the origin of both electroluminescence and photoluminescence.en-USJournal Article2011-08-0310.1063/1.3157274
