Stacking-Induced Tuning of a Flat-Band Surface State in NbIrTe4
Jiabin Yu, Mohamed Oudah, Giang Nguyen +12
Ternary layered transition metal dichalcogenides (TMDCs) offer high tunability and access to correlated and topological states. However, like the broader family of layered TMDCs, t…
Extended Hubbard Model realized in 2D clusters of molecular anions
Oliver Tong, Katherine A. Cochrane, Bingkai Yuan +3
The Hubbard model, despite its simplicity, is remarkably successful at describing numerous many-body phenomena. However, due to the small class of problems which can be solved exac…
Intrinsic defect intolerance in the ultra-pure metal PtSn
Samikshya Sahu, Dong Chen, Niclas Heinsdorf +6
Ultra-pure materials are highly valued as model systems for the study of intrinsic physics. Frequently, however, the crystal growth of such pristine samples requires significant op…
Quasiparticle interference in LiFeAs: Signature of inelastic tunneling through spin fluctuations
Shun Chi, Carolina A. Marques, Walter N. Hardy +5
Quasiparticle interference (QPI) is a powerful tool to characterize the symmetry of the superconducting order parameter in unconventional superconductors, by mapping the spatial de…
Quenching of excitons at grain boundaries in C60 thin films
Rysa Greenwood, Bradley G. Guislain, MengXing Na +12
Exciton lifetimes play a critical role in the performance of organic optoelectronic devices. In this work, we investigate how the presence of multiple rotational domains, and there…
Using -means to sort spectra: electronic order mapping from scanning tunneling spectroscopy measurements
V. King, Seokhwan Choi, Dong Chen +7
Hyperspectral imaging techniques have a unique ability to probe the inhomogeneity of material properties whether driven by compositional variation or other forms of phase segregati…
Two-stage growth for highly ordered epitaxial C films on Au(111)
Alexandra B. Tully, Rysa Greenwood, MengXing Na +13
As an organic semiconductor and a prototypical acceptor molecule in organic photovoltaics, C has broad relevance to the world of organic thin film electronics. Although high…
Selective Hybridization of a Terpyridine-Based Molecule with a Noble Metal
M. Capsoni, A. Schiffrin, K. A. Cochrane +5
The electronic properties of metal-molecule interfaces can in principle be controlled by molecular design and self-assembly, yielding great potential for future nano- and optoelect…
Quasiparticle interference observation of the topologically non-trivial drumhead surface state in ZrSiTe
B. A. Stuart, Seokhwan Choi, Jisun Kim +6
Drumhead surface states that link together loops of nodal lines arise in Dirac nodal-line semimetals as a consequence of the topologically non-trivial band crossings. We used low-t…
Sign inversion in the superconducting order parameter of LiFeAs inferred from Bogoliubov quasiparticle interference
Shun Chi, S. Johnston, G. Levy +10
Quasiparticle interference (QPI) by means of scanning tunneling microscopy/spectroscopy (STM/STS), angle resolved photoemission spectroscopy (ARPES), and multi-orbital tight bind-…
Quantifying many-body effects by high-resolution Fourier transform scanning tunneling spectroscopy
S. Grothe, S. Johnston, Shun Chi +3
Many-body phenomena are ubiquitous in solids, as electrons interact with one another and the many excitations arising from lattice, magnetic, and electronic degrees of freedom. The…
Bound States of Defects in Superconducting LiFeAs Studied by Scanning Tunneling Spectroscopy
S. Grothe, Shun Chi, P. Dosanjh +5
Defects in LiFeAs are studied by scanning tunneling microscopy (STM) and spectroscopy (STS). Topographic images of the five predominant defects allow the identification of their po…
Scanning tunneling spectroscopy of superconducting LiFeAs single crystals: Evidence for two nodeless energy gaps and coupling to a bosonic mode
Shun Chi, S. Grothe, Ruixing Liang +5
The superconducting compound, LiFeAs, is studied by scanning tunneling microscopy and spectroscopy. A gap map of the unreconstructed surface indicates a high degree of homogeneity…
