摘要: The excitation spectrum of a slab normal metal deposited on superconducting substrate is discussed. It shown that if the electron- electron attractive interaction negligibly small in metal, there no energy gap even thickness alab small. effect may possibly explain some peculiar results tunneling experiments hard superconductors.
