摘要：

Without giving or citing a derivation, Maki and Haas [Phys. Rev. B 67, 020510 (2003)] presented a formula for coherent tunneling between identical d(x2)-y(2)-wave superconductors twisted about the c axis, which they claimed accounted for Andreev reflections at the grain boundary. However, their formula does not reduce to known results in the appropriate limits, casting serious doubt upon its validity, and upon its applicability to the cross-whisker data on Bi2Sr2CaCu2O8+delta by Takano [Phys. Rev. B 65, 140513 (2002)] they tried to fit.
