DOIAbstract
Bi2Sr2CaCu2Oy single crystal was studied by means of high-resolution X-ray diffraction and the local work function measurement with scanning tunneling microscope (STM). The results show that the single crystal is natively inhomogeneous. The rocking curve of 0 0 1 reflection indicates that the c-axis lattice constant of the crystal varies in a narrow range, clearly showing a multi-layer character. The reflectivity measurement supports this result. It shows an obvious multi-layer character too. The small angle scattering, indicates that although the c-axis lattice constant is little different in the crystal. it shows a long period of about 340 Angstrom. The local work function measurement with STM demonstrates that the crystal is inhomogeneou...
