Doubly-charged silicon vacancy center, photochromism, and Si-N complexes in co-doped diamond
B G Breeze, C J Meara, X X Wu +13
We report the first experimental observation of a doubly-charged defect in diamond, SiV2-, in silicon and nitrogen co-doped samples. We measure spectroscopic signatures we attribut…
Observation of topological transition in high-T superconductor FeTeSe/SrTiO(001) monolayers
X. -L. Peng, Y. Li, X. -X. Wu +12
Superconductors with topological surface or edge states have been intensively explored for the prospect of realizing Majorana bound states, which obey non-Abelian statistics and ar…
Disentangling the surface and bulk electronic structures of LaOFeAs
P. Zhang, J. Ma, T. Qian +7
We performed a comprehensive angle-resolved photoemission spectroscopy study of the electronic band structure of LaOFeAs single crystals. We found that samples cleaved at low tempe…
Cooper Pairing and Phase Coherence in Iron Superconductor Fe1+x(Te,Se)
J. -X. Yin, Zheng Wu, X. Huang +14
The Cooper pairing and phase coherence are two fundamental aspects of superconductivity. Due to breaking time reversal symmetry, magnetic impurities are detrimental to superconduct…
Orbital selectivity of layer resolved tunneling on iron superconductor Ba0.6K0.4Fe2As2
J. -X. Yin, X. -X. Wu, Jian Li +15
We use scanning tunneling microscopy/spectroscopy (STM/S) to elucidate the Cooper pairing of the iron pnictide superconductor Ba0.6K0.4Fe2As2. By a cold-cleaving technique, we obta…
Observation of a Robust Zero-energy Bound State in Iron-based Superconductor Fe(Te,Se)
J. -X. Yin, Zheng Wu, J. -H. Wang +14
A robust zero-energy bound state (ZBS) in a superconductor, such as a Majorana or Andreev bound state, is often a consequence of non-trivial topological or symmetry related propert…
Strain tuning of optical emission energy and polarization in monolayer and bilayer MoS2
G. Wang, C. R. Zhu, B. L. Liu +7
We use micro-Raman and photoluminescence (PL) spectroscopy at 300K to investigate the influence of uniaxial tensile strain on the vibrational and optoelectronic properties of monol…
