発明の名称 (英語) Carbon nanotube field-effect transistor
発明の概要(英語) A single-electron transistor comprising at least a substrate (1), a source electrode (3) and a drain electrode (4) formed on top of the substrate (1) opposing to each other, and a channel arranged between the source electrode (3) and the drain electrode (4) is disclosed wherein the channel is composed of ultra fine fibers (CNT) (7).
By having such a constitution, a sensor can have excellent sensitivity.
特許請求の範囲(英語) [claim1]
1. A sensor comprising at least a substrate (1), a source electrode (3) and a drain electrode (4) formed on top of said substrate (1) opposing to each other, and a channel arranged between said source electrode (3) and said drain electrode (4), wherein said channel is composed of ultra fine fibers,
wherein a gate electrode is formed in a site of said substrate other than the positions where said source electrode (3) and said drain electrode (4) are placed, wherein a SiO2 film on the substrate (1) on an opposite side to the channel is molecule-modified by a specific substance (13) interacting with a substance to be detected, and
such that a sample solution (15) containing substance to be detected (14) can be put between the modified substrate and the gate electrode (8).
[claim2]
2. A sensor according to claim 1, wherein said ultra fine fibers are nanotube-like structures.
[claim3]
3. A sensor according to claim 2, wherein said nanotube-like structures are carbon nanotubes (7).
[claim4]
4. A sensor according to claim 2 or 3, wherein a defect is introduced into said nanotube-like structures.
[claim5]
5. A sensor according to claim 1, wherein said substance to be detected (14) and said specific substance (13) are biopolymers interacting with each other.
[claim6]
6. A sensor according to claim 5, wherein said substance to be detected (14) is an antigen or an antibody, and said specific substance is an antibody or an antigen.
