PROBLEM TO BE SOLVED: To provide a gas sensor capable of performing gas detection with high sensitivity and high selectivity by using a graphene channel layer which is capable of polarity control.SOLUTION: The gas sensor is constituted of: a channel layer 2 which is joined with an F terminal GNR2b, an H terminal GNR2a and a F terminal GNR2c the ends of which are terminated with a modified group different from each other; a source electrode 3 which is formed at one end of a channel layer 2; and a drain electrode 4 which is formed at the other end of the channel layer 2. The surface of the H terminal GNR2a is exposed, and the exposed part is a gas detection section 10.SELECTED DRAWING: Figure 7 |
