The authors have studied the feasibility of making sharp and clean electrical contacts with high-temperature superconductors by cleaving single-crystal Y-Ba-Cu-O and Bi-Sr-Ca-Cu-O films in a stream of evaporated noble metals forming SN (superconductor/normal metal) contacts at the revealed cross-sectional edge surfaces of the films. With this technique, contact resistances on the order of 10/sup -9/ to 10/sup -8/ Omega cm/sup 2/ have been consistently obtained. For a structure with an oxide/Au/oxide configuration, the interface resistance was found to show a flat temperature dependence below T/sub c/. Material dependence and anisotropy were observed in the contact resistance. When
