Abstract
We analyse bulk properties of d-wave superconductor, which is consider ed relevant to high T(c) superconductor, within weak coupling theory. The electronic density of states exhibits a lograthismic peak at E=DEL TA. Further if we identify this DELTA with energy gap, we obtain DELTA (O)/T(c)=2.14 somewhat larger than the BCS value. These are rather con sistent with experimental observation.
