Nanostructured led

A nanostructured LED comprising:

• a plurality of nanowires;
• a substrate;
• and
• at least one group of contact pads;
• wherein:
• each of the plurality of nanowires protrudes from the substrate and each nanowire comprises a pn- or p-i-n-junction;
• a top portion of each nanowire or at least one group of nanowires from the plurality of nanowires is covered with a light-reflecting or transparent contact layer to form at least one contact group of nanowires;
• the at least one group of contact pads is in electrical contact with a bottom portion of each of the plurality of nanowires;
• the light-reflecting or transparent contact layer is in electrical contact with the at least one group of contact pads via the pn- or p-i-n-junction;
• and
• the at least one group of contact pads is a first group of contact pads in which the contact pads are distributed and separated from each other to reduce an average serial resistance.

A nanostructured LED comprising:

• a first group of contact pads;
• and
• a second group of contact pads;
• a carrier structure;
• a first plurality of bumps electrically connecting the first group of contact pads to the carrier structure;
• and
• a second plurality of bumps electrically connecting a second group of contact pads to the carrier structure;
• wherein:
• each of the plurality of nanowires protrudes from the substrate and each nanowire comprises a semiconductor pn- or p-i-n-junction;
• a top portion of at least one group of nanowires from the plurality of nanowires is covered with a light-reflecting contact layer to form at least one contact group of nanowires;
• the first group of contact pads is in electrical contact with a bottom portion of each of the plurality of nanowires;
• and
• the second group of contact pads is in electrical contact with the light-reflecting contact layer.
