Claim:
1. A semiconductor device comprising: a nanowire structure formed between a source region and a drain region, the nanowire structure having a first band gap energy section joined with a second band gap energy section, the first band gap energy section being joined to the source region and having a band gap energy level greater than the band gap energy level of the second band gap energy section, the second band gap energy section being joined to the drain region, the first band gap energy section being composed of a single first material, and the second band gap energy section being composed of a single second material that (i) has a lower conduction band level than does the first band gap energy section and (ii) has a higher valence band than does the first band gap energy section; a junction at which the first band gap energy section is joined to the first band gap energy section, such that a gate region formed around the junction.
