摘要：
We calculate I-c( T) and R-n for both coherent and incoherent electron tunneling across a c-axis break junction between two nu=s,d(x2-y2)-wave layered superconducting half spaces, each with c-axis bandwidth 2J. Coherent quasiparticle tunneling only occurs for voltages V<2J/e, leading to difficulties in measuring R-n for under-doped samples. The coherent part of I-c(0) is independent of Delta(nu)(0) for J/Delta(nu)(0)much less than 1, and can be large. Our results are discussed with regard to recent experiments. [S0163-1829(98)01745-7].
