Outline of Final Research Achievements |
We have developed terahertz (THz) emitters by using single crystals of high temperature superconductor Bi2Sr2CaCu2O8+d (Bi2212). In order to understand the radiation output power from Bi2212-THz emitters, we studied relationship between the thickness of Bi2212 crystals used for the emitters and the radiation output power. As a result, the radiation output power tends to increase with increasing the thickness of Bi2212 single crystals up to 5μm. This behavior seems to be understood by considering the number of Josephson junctions in the mesa structures of Bi2212 single crystals and the radiation efficiency determined by the shape and size of the mesa structures. We also improved the device structure of Bi2212-THz emitters in order to remove Joule heating generated in the device. By the reduction of Joule heating on the devices, the radiation frequencies ranging from 0.3 to 2.4 THz can be obtained by adjusting the shape and size of the mesa structures.
