摘要：

Measurements of differential resistance as a function of voltage bias for normal: superconductor point contacts of Ag:Nb, Cu:Nb and Al:Nb were made as a function of temperature. Andreev reflection of the charge carriers at the normal: superconductor interface is clearly observed. Good agreement between experiment and theory is obtained in the point contact (metallic microstriction) range. © 1990, Elsevier Science Publishers B.V. (North-Holland). All rights reserved.
