Abstract: A gas sensor that can enhance gas detection sensitivity more than the conventional sensors with a simple configuration is proposed. An electric double layer including a gate insulating layer is formed in an ionic liquid (IL), a change of a state of the gate insulating layer in the ionic liquid (IL) that occurs by absorbing a gas is directly reflected in a source-drain current (Isd) that flows in a carbon nanotube (8). Therefore, the gas detection sensitivity can be enhanced more than in the conventional sensors. Further, since the ionic liquid (IL) can be simply provided on a substrate (2) to be in contact with the carbon nanotube (8) and a gate electrode (7), the configuration that chemically modifies a surface of the carbon nanotube with a plurality of polymers as in the conventional gas sensors is not needed, and the configuration can be simplified correspondingly.

Abstract: To propose a gas sensor and a gas sensor structural body that can improve detection sensitivity of gas more than in the conventional gas sensors with a simple configuration. A graphene (8) between a source electrode (3) and a drain electrode (4) is provided in an ion liquid (L), whereby a state change of charges in the ion liquid (L) caused by absorption of gas is directly reflected on a source-drain current (Isd) that flows in the graphene (8). Therefore, it is possible to improve detection sensitivity of the gas more than in the conventional gas sensors. The graphene (8) only has to be provided to be disposed in the ion liquid (L). Therefore, unlike in the conventional gas sensors, a configuration in which carbon nanotubes are surface-chemically modified by a plurality of polymers is unnecessary. Therefore, it is possible to simplify a configuration.

Abstract: A gas sensor is proposed, which can detect a gas by a novel configuration while reduction in size is achieved. The gas sensor (1) does not need a light absorption path as in a prior art so that the size can be reduced correspondingly. Further, in the gas sensor (1), a gas is absorbed in an ionic liquid (IL), and a dielectric constant of the ionic liquid (IL) that changes by absorbing the gas can be measured according to a change in light intensity that occurs by a surface plasmon resonance phenomenon in a metal layer (7). Thus, the gas sensor (1) including the novel configuration that can detect a gas based on the change in the light intensity can be realized.
