| Abstract(in English) | We have been successfully fabricated an integrated THz oscillator stack with detector stack in Bi_2Sr_2CaCu_2O_<8+δ> (Bi-2212) single crystal by using photolithography and dilute acid solution (pH=1.65). These stacks were formed in a same crystal, which were isolated by BiOCl crystal. Lateral dimensions of the oscillator IJJ stacks were more than several hundred μm^2, while detector stack was about 10×10 μm^2. In order to confirm emission of electromagnetic waves from the oscillator stack, a zero voltage current for the detector stack was measured while sweeping DC bias of the oscillator stack. In liquid nitrogen, we found that the zero voltage current of the detector stacks was strongly suppressed when the oscillator stacks was biased at hump structure in the I-V curve. However, the hump structure could not been observed at 77 K achieved by cooling gas such as N_2 or He. This result indicates that the oscillation characteristics in the large sized Bi-2212 IJJs have a strong influence on cooling method. |
