Abstract
We performed a photoemission microscopy study on cleaved surfaces of a Bi2Sr2CaCu2O81d single crystal. Our findings show that pronounced inhomogeneity effects exist even on good quality single crystals. The length scale of the observed features ranges from a few microns to a few hundred microns. We discuss the importance of our results for the interpretation of conventional photoemission experiments on Bi2Sr2CaCu2O81d which typically probe an area of the order of 1 mm2File in questo prodotto:
