Nanowhiskers with pn junctions and methods of fabricating thereof

Abstract From the Canadian patent

Nano-engineered structures are disclosed incorporating nanowhiskers of high , mobility conductivity and incorporating pn junctions. In one embodiment a , nanowhisker of a first semiconducting material has a first band gap and an , enclosure comprising at least one second material with a second band gap encloses said nanoelement along at least part of its length the second , material being doped to provide opposite conductivity type charge carriers in respective first and second regions along the length of the of the nanowhisker, whereby to create in the nanowhisker by transfer of charge carriers into the nanowhisker, corresponding first and second regions of opposite conductivity type …
