【 摘 要 】

The results obtained by their group in thin film fabrication and STM tunneling on superconducting borocarbides YNi(sub 2)B(sub 2)C have been be briefly reviewed. Results concerning the microwave surface impedance and the S/N planar junctions on LuNi(sub 2)B(sub 2)C thin films have been also presented and analyzed. These new data unambiguously confirm the full BCS nature of the superconducting gap in borocarbides and the absence of significant pair-breaking effects in LuNi(sub 2)B(sub 2)C.
