Abstract
Techniques for ultra-sensitive detection are provided. In one aspect, a detection device is provided. The detection device comprises a source; a drain; a nanowire comprising a semiconductor material having a first end clamped to the source and a second end clamped to the drain and suspended freely therebetween; and a gate in close proximity to the nanowire.
Claims14
A molecular detection device comprising:
- a source;
- a drain;
- a nanowire comprising a semiconductor material having a first end clamped to the source and a second end clamped to the drain, wherein at least a portion of a surface of the nanowire is charge-sensitized by the introduction of compounds to the surface;
- and
- a gate, at least a portion of which is separated from one or more of the source and the drain by a dielectric substrate.
