Abstract:
1. A semiconductor device comprising a semiconductor nanoelement protruding from a semiconductor substrate, the semiconductor device arranged to be electrically connectable, wherein: a masking layer is arranged on the semiconductor substrate, the masking layer comprising at least one through hole; the nanoelement is extending through the through hole; a semiconductor volume element having a larger diameter than the nanoelement is arranged in epitaxial connection to the nanoelement and expanding above the masking layer; the nanoelement comprises an undoped semiconductor which is intrinsically first conductivity type; the semiconductor volume element comprises a heavily doped semiconductor of a second conductivity type different from the first conductivity type; the nanoelement comprises a first part of a pn junction; and the volume element comprises a second part of the pn junction, wherein the pn junction provides a recombination centre arranged to produce light.
