Abstract

The present invention relates to semiconductor devices comprising semiconductor nanoelements. In particular the invention relates to devices having a volume element having a larger diameter than the nanoelement arranged in epitaxial connection to the nanoelement. The volume element is being doped in order to provide a high charge carrier injection into the nanoelement and a low access resistance in an electrical connection. The nanoelement may be upstanding from a semiconductor substrate. A concentric layer of low resistivity material forms on the volume element forms a contact.
