Abstract:
1. A semiconductor device comprising: a semiconductor nanowire, a first semiconductor pad located on a substrate and comprising a semiconductor material; a first semiconductor pad located on said substrate and laterally contacting a first end portion of said semiconductor nanowire; a second semiconductor pad located on said substrate and laterally contacting a second end portion of said semiconductor nanowire, wherein said semiconductor material of said semiconductor nanowire contiguously extends from said first end to said second end, and has a same dopant concentration between said first end and said second end; and a chemical coating layer located on said semiconductor nanowire and comprising a functional material that bonds with at least one type of charged molecule, wherein free charge carrier density in said semiconductor nanowire is altered upon bonding of said at least one type of charged molecule and said functional material.
