内容記述 |
We report STM/STS measurements at 8 K in underdoped Bi2Sr2CaCu2O8+delta crystals (T-c = 76 K and hole-doping level p similar to 0.12) whose energy spectra around the Fermi level are characterized by a two-gap structure consisting of spatially inhomogeneous pseudogap (PG) and comparatively homogeneous superconducting gap (SCG). Two electronic superstructures, checkerboard modulation (CBM) and Cu-O-Cu bond-centered modulation (BCM), are observed with mapping spectral weights at low energies within the SCG and the ratio of spectral weights at +/-Delta(PG) (PG energy), respectively. On the basis of the present findings, we suggest that the lower-energy scale CBM is an intrinsic property of Cu-O planes and can coexist with the BCM whose characteristic energy is similar to Delta(PG) in identical regions in real space. |
