Abstract
Current transport in micron-sized normal-metal-high-temperature superconductor heterojunctions (Au/YBa2Cu3O6+x ) was studied for two crystallographic orientations of YBCO films. It is shown that depending on the transport-current flow direction relative to the crystallographic axes of the YBCO film, the electronic transport properties of Au/YBCO heterojunctions with highly transparent boundaries change from quasi-tunneling (along the YBCO c axis) to close-to-Ohmic (in the directions lying in the YBCO basal plane).
