Patent ID: 8664636

Claim:
A nanostructured device comprising: a first group of nanowires protruding from a substrate where each nanowire of the first group of nanowires comprises at least one pn- or p-i-n-junction, a first contacting feature that at least partially encloses and electrically connects to a first side of the pn- or p-i-n-junction of each nanowire in the first group of nanowires, and a second contacting feature, which comprises a second group of nanowires that protrudes from the substrate, and which is arranged to provide an electrical connection to a second side of the pn or p-i-n junction of each nanowire in the first group of nanowires, wherein the pn- or p-i-n junction of each nanowire in the first group of nanowires in operation provides an active region for charge carrier recombination for generation of light such that the nanostructured device functions as a LED device, wherein the second contacting feature further comprises a second contact at least partly enclosing the nanowires of the second group of nanowires, and wherein a pn- or p-i-n junction of each nanowire in the second group of nanowires is shorted by the second contact to render the second group of nanowires electrically inactive.
