Direct growth of germanene at interfaces between van der Waals materials and Ag(111)
Seiya Suzuki, Takuya Iwasaki, K. Kanishka H. De Silva +7
Germanene, a two-dimensional honeycomb germanium crystal, is grown at graphene/Ag(111) and hexagonal boron nitride (h-BN)/Ag(111) interfaces by segregating germanium atoms. A simpl…
Two-dimensional atomic layer-molecule hybrid superconductors with controllable exchange coupling
Shunsuke Yoshizawa, Emi Minamitani, Saranyan Vijayaraghavan +6
The coexistence and competition of superconductivity and magnetism can lead to a variety of rich physics and technological applications. Recent discovery of atomic-layer supercondu…
Locality and lateral modulations of quantum well states in Ag(100) thin films studied using a scanning tunneling microscope
Takashi Uchihashi, Tomonobu Nakayama
We investigate Ag(100) thin films epitaxially grown on a Fe(100) substrate using a low-temperature scanning tunneling microscope. Fabrication of a wedge structure by evaporating Ag…
Imaging Josephson Vortices on the Surface Superconductor Si(111)-(root7xroot3)-In using a Scanning Tunneling Microscope
Shunsuke Yoshizawa, Howon Kim, Takuto Kawakami +5
We have studied the superconducting Si(111)-(root7xroot3)-In surface using a 3He-based low-temperature scanning tunneling microscope (STM). Zero-bias conductance (ZBC) images taken…
Macroscopic Superconducting Current through a Silicon Surface Reconstruction with Indium Adatoms: Si(111)-(R7R3)-In
Takashi Uchihashi, Puneet Mishra, Masakazu Aono +1
Macroscopic and robust supercurrents are observed by direct electron transport measurements on a silicon surface reconstruction with In adatoms (Si(111)-(R7xR3)-In). The supercondu…
One-dimensional surface states on a striped Ag thin film with stacking fault arrays
Takashi Uchihashi, Puneet Mishra, Katsuyoshi Kobayashi +1
One-dimensional (1D) stripe structures with a periodicity of 1.3 nm are formed by introduction of stacking fault arrays into a Ag thin film. The surface states of such striped Ag t…
Strong Electron Confinement By Stacking-fault Induced Fractional Steps on Ag(111) Surfaces
Takashi Uchihashi, Katsuyoshi Kobayashi, Tomonobu Nakayama
The electron reflection amplitude at stacking-fault (SF) induced fractional steps is determined for Ag(111) surface states using a low temperature scanning tunneling microscope…
History and metastability effects in the intermediate state of mesoscopic type I superconducting Indium
Ajay D. Thakur, Ujjal K. Gautam, Goutam Sheet +5
We report detailed magnetic measurements on history and metastability effects in the intermediate state of mesoscopic cylinders of type I superconducting Indium. This includes the…
Temperature suppression of STM-induced desorption of hydrogen on Si(100) surfaces
C. Thirstrup, M. Sakurai, T. Nakayama +1
The temperature dependence of hydrogen (H) desorption from Si(100) H-terminated surfaces by a scanning tunneling microscope (STM) is reported for negative sample bias. It is found…
