Abstract:
1. A nanogap device comprising: a dielectric membrane on a front-side surface of a semiconductor substrate; a first capped nanowire structure located on a first portion of said dielectric membrane; and a second capped nanowire structure located on a second portion of said dielectric membrane, wherein said first capped nanowire structure and said second capped nanowire structure are separated by a nanogap of less than 3 nanometers, the nanogap being formed through a nanowire but not through the dielectric membrane; wherein said first capped nanowire structure includes a first nanowire portion, a first metal pad directly on top of said first nanowire portion, and a first anti-retraction capping material portion directly on top of said first metal pad; wherein said second capped nanowire structure includes a second nanowire portion, a second metal pad directly on top of said second nanowire portion, and a second anti-retraction capping material portion directly on top of said second metal pad; wherein said first nanowire portion and said second nanowire portion comprise a same metal, said same metal selected from the group consisting of palladium and platinum.
