Organic semiconductor material and organic thin-film transistor

An organic field effect transistor including an organic semiconductor layer constituting a current path between a source electrode and a drain electrode wherein the organic semiconductor layer is made of a conjugated polymer having a depletion layer and a conductivity of the organic semiconductor layer is controlled by using a gate electrode, wherein the depletion layer is formed by joining a reductive material being capable of forming Schottky contact with the organic semiconductor layer made of the conjugated polymer. There can be provided an organic field effect transistor using a conjugated polymer as an organic semiconductor and being capable of maintaining an insulation property.

Organic field effect transistor

To provide an actuator that can flexibly and softly move like muscles, can maintain a stable operation over a long period of time, can generate a strong driving force, has a rapid input response, has a favorable sensitivity, has a high energy conversion efficiency, and can be accurately controlled, a coil is embedded in a magnetic elastomer obtained by mixing a powder-like ferromagnetic or highly magnetic permeable material with an elastomer, so that the coil can be electrically connected. By electrically connecting the coil, a magnetic field generates in the coil and around the coil. The magnetic field penetrates the magnetic elastomer. When the magnetic field generates in the magnetic elastomer, deformation force acts on the magnetic elastomer by the magnetic force acting on each portion in the magnetic elastomer. Thus, driving force can be obtained.
