Scanning Tunneling Spectroscopic Studies of Cuprate Superconductors
N. -C. Yeh, C. -T. Chen, R. P. Vasquez +4
Quasiparticle tunneling spectra of both hole-doped (p-type) and electron-doped (n-type) cuprates are studied using a low-temperature scanning tunneling microscope. The results reve…
Strongly correlated s-wave pairing in the n-type infinite-layer cuprate
C. -T. Chen, P. Seneor, N. -C. Yeh +7
Quasiparticle tunneling spectra of the electron-doped (n-type) infinite-layer cuprate Sr_{0.9}La_{0.1}CuO_2 reveal characteristics that counter a number of common phenomena in the…
X-ray Photoemission Study of MgB2
R. P. Vasquez, C. U. Jung, Min-Seok Park +3
A c-axis oriented thin film and a high density sintered pellet of MgB2 have been studied by x-ray photoemission spectroscopy, and compared to measurements from MgO and MgF2 single…
X-ray Photoemission Study of the Infinite-Layer Cuprate Superconductor Sr0.9La0.1CuO2
R. P. Vasquez, C. U. Jung, J. Y. Kim +3
The electron-doped infinite-layer superconductor Sr0.9La0.1CuO2 is studied with x-ray photoemission spectroscopy (XPS). A nonaqueous chemical etchant is shown to effectively remove…
Spectroscopic Evidence for Anisotropic S-Wave Pairing Symmetry in MgB2
P. Seneor, C. -T. Chen, N. -C. Yeh +7
Scanning tunneling spectroscopy of superconducting MgB ( K) were studied on high-density pellets and c-axis oriented films. The sample surfaces were chemically etched…
