Uncovering the Electronic States of the Pseudogap Thursday, February 12, 2004 We performed a scanning tunneling spectrocopy characterization of the electronic correlations in the pseudogap state in a high-Tc superconductor. Heating a normal superconductor above its critical temperature results in a normal metallic behavior, but heating a high-temperature superconductor above its critical temperature results in a unique non-metallic state called the pseudogap state. We have examined for the first time the motion of electrons in this mysterious pseudogap state on the nanometer scale. The study reveals that the electrons from a energy independent checkerboard pattern in this state. “;Local Ordering in the Pseudogap State of a High-Tc Superconductor,” M. Vershinin, S. Misra, S. Ono, Y. Abe, Y. Ando, and A. Yazdani, Science 303 1995, (2004).
