Abstract(in English) | Transport properties of small-sized intrinsic josephson in Bi_2Sr_2CaCu_2O_y have been systematically investigated with respect to both junction size and temperature. Using electron-beam lithography, we have successfully fabricated mesas with lateral dimensions ranging from sub-μm^2 to several tens μm^2 on the same crystal. The fabricated mesas showed typical multiple resistive branches with hysteresis and well defined gap structures in the I-V characteristics. In addition, the suppression of the critical current densities for mesas with dimensions less that 1 μm^2 were observed. Such decrease in J_c was interpreted in terms of the contribution of the Coulomb blockade effect. |
