| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We experimentally investigated the photomixing function in the millimeter wave range by using InGaAs channel high electron mobility transistors (HEMTs) and graphene channel field effect transistors (FETs) which we fabricated. The dual comb IR laser beam having differential frequency 12.5, 25 or 37.5 GHz was introduced to the channel area from the backside of the device and we measured the photoresponse spectrum of the downconverted output. The maximam photoresponse of the InGaAs channel HEMT was obtained at the threshold voltage. We also obtained the photoresponse of the graphene channel FET in spite of its poor current-gain cutoff frequency of 2GHz. | |
