Clear atomic images of Bi2Sr2CaCu208+ ~ cleaved surfaces were observed at 4.2 K and 300 K by using scanning tunneling microscopy (STM). The atomic image taken under bias voltages much lower than the semiconducting gap of the Bi-O plane is of a square-lattice, which seems to be of the Cu-O plane. A m
Scanning tunneling microscopy (STM) measurements have shown that electronic states at the surface of Bi 2 Sr 2 CaCu 2 O 8þd single crystals form standing wave patterns at temperatures far below the superconducting transition. It has been shown that these patterns are consistent with those expected f
