With an overlap structure for improving coupling, intrinsic Josephson junctions (IJJs) with an a-b plane area down to 1 μm2 were fabricated on argon-annealed Bi2Sr2CaCu2O8+x single crystals. Responses at frequencies from a few to 200 gigahertz were carefully investigated by measuring the samples' current-voltage (I-V) curves. The experimental results indicate that high frequency applications of IJJs over a very wide frequency range are potentially possible.
