Coulomb gap induced by electronic correlation and enlarged superconducting gap in laterally confined Pb islands grown on SrTiO3
Yonghao Yuan, Xintong Wang, Canli Song +6
We report high-resolution scanning tunneling microscopy (STM) study of nano-sized Pb islands grown on SrTiO3, where three distinct types of gaps with different energy scales are re…
Edge states at nematic domain walls in FeSe films
Yonghao Yuan, Wei Li*, Bin Liu +9
Quantum spin Hall (QSH) effect is an intriguing phenomenon arising from the helical edge states in two-dimensional topological insulators. We use molecular beam epitaxy (MBE) to pr…
Gate-Variable Mid-Infrared Optical Transitions in a Topological Insulator
William S. Whitney, Victor W. Brar, Yunbo Ou +6
We report mid-infrared spectroscopy measurements of an electrostatically gated topological insulator, in which we observe several percent modulation of transmittance and reflectanc…
Nodeless pairing in superconducting copper-oxide monolayer films on Bi2Sr2CaCu2O8+δ
Yong Zhong, Yang Wang, Sha Han +13
The pairing mechanism of high-temperature superconductivity in cuprates remains the biggest unresolved mystery in condensed matter physics. To solve the problem, one of the most ef…
Simultaneous electrical-field-effect modulation of both top and bottom Dirac surface states of epitaxial thin films of three-dimensional topological insulators
Cui-Zu Chang, Zuocheng Zhang, Kang Li +11
It is crucial for the studies of the transport properties and quantum effects related to Dirac surface states of three-dimensional topological insulators (3D TIs) to be able to sim…
Molecular beam epitaxy growth and scanning tunneling microscopy study of TiSe ultrathin films
Jun-Ping Peng, Jia-Qi Guan, Hui-Min Zhang +5
Molecular beam epitaxy is used to grow TiSe2 ultrathin films on graphitized SiC(0001) substrate. TiSe2films proceed via a nearly layer-by-layer growth mode and exhibit two dominant…
