Abstract: An inductor component that includes a core that includes a substantially column-shaped shaft part and a pair of support parts at both ends of the shaft part; terminal electrodes that are respectively provided on the pair of support parts; and a wire that is wound around the shaft part and has end portions that are respectively connected to the terminal electrodes on the pair of support parts. The inductor component exhibits an impedance value of 2100? or higher for an input signal having a frequency of 500 MHz.

Abstract: A tunnel field effect transistor is capable of operating at a low subthreshold and is able to be manufactured easily. The tunnel field effect transistor includes a group IV semiconductor substrate having a (111) surface and doped so as to have a first conductivity type, a group III-V compound semiconductor nanowire arranged on the (111) surface and containing a first region connected to the (111) surface and a second region doped so as to have a second conductivity type, a source electrode connected to the group IV semiconductor substrate; a drain electrode connected to the second region, and a gate electrode for applying an electric field to an interface between the (111) surface and the group III-V compound semiconductor nanowire, or an interface between the first region and the second region.
