Abstract

We have investigated the properties of sub-micron intrinsic Josephson junctions (IJJs) fabricated on Bi2Sr2CaCu 2O8+δ liquid phase epitaxy film. The IJJs with junction area S < 2 μm2 showed individual current-voltage curves, which have suppressed 1st branch and unsuppressed other branches. This suppression was observed systematically as an increase the ratio of charging energy and Josephson coupling energy. It is expected that such suppressions are due to charging effect in IJJs.
