| Outline of Final Research Achievements |
Graphene is known to have small electron heat capacity and electron-phonon interaction. Hence, an electron temperature of the graphene is very sensitive to the external stimuli and can be controlled nearly independent from its lattice temperature. By using this property, we developed a method to control electron heat transfer in graphene. We demonstrate a black body radiation and infrared photo-detection using graphene devices. These finding could be useful for the application to a far-infrared to terahertz optoelectronic devices.
