| Abstract(in English) | YBa_2Cu_3O_<7-y>(YBCO) film Josephson junctions(JJ) on silicon(Si) substrate were fabricated by focused electron beam irradiation. We used approximately 400Å thick TBCO films on Si substrates with buffer layers of Y_2O_3 and yttria stabilized ZrO_2(YSZ). Microbridges 2～5μm in width and 10μm in length on YBCO films were patterned using the EDTA etchant. The 200KeV electron beam irradiation was performed by STEM to introduce a weak link across the bridge to form a junction. The junctions showed RSJ-like I-V curves and magnetic field modulation of the critical current. Shapiro steps induced by irradiation of 20GHz were observed in dV/dI-V curves up to about 4m V which suggests that the junction can respond up to about 2THz. |
