Abstract
We patterned small size mesa structures on top of single crystals of the hi gh temperature superconductor Bi2Sr2CaCu2O8+delta using a combination of ph otolithography and electron beam lithography. The mesas consisted typically of 4-12 intrinsic Josephson junctions formed between adjacent CuO2 double layers. The smallest lateral mesa size was 1 mum We discuss the electrical properties of these stacks including current-voltage characteristics and cr itical current vs, external magnetic fields applied parallel to the layers.
