Title: Emergence of topological and trivial interface states in VSe₂ films coupled to Bi₂Se₃

Abstract

Coupling ordinary metals with topological Bi₂Se₃ can instigate the long-range migration of the spin-polarized Dirac states. Instead, for trivial metallic VSe₂ films on Bi₂Se₃, topological and trivial Rashba-type interface states emerge, each strongly localized at the VSe₂/Bi₂Se₃ interface. Their rapidly decaying spectral weights are uncovered by thickness-dependent band mappings of VSe₂ films and replicated by a phenomenological first-principles model of the spectral function. In this work, the results are pertinent to spintronic devices requiring spin transmission across metal/topological insulator interfaces.

Dirac Nodal Line in Hourglass Semimetal Nb₃SiTe₆

Journal Article Liu, Ro-Ya ; Huang, Angus ; Sankar, Raman ; ... - Nano Letters

Glide-mirror symmetry in nonsymmorphic crystals can foster the emergence of novel hourglass nodal loop states. Here, we present spectroscopic signatures from angle-resolved photoemission of a predicted topological hourglass semimetal phase in Nb₃SiTe₆. Linear band crossings are observed at the zone boundary of Nb₃SiTe₆, which could be the origin of the nontrivial Berry phase and are consistent with a predicted glide quantum spin Hall effect; such linear band crossings connect to form a nodal loop. Furthermore, the saddle-like Fermi surface of Nb₃SiTe₆ observed in our results helps unveil linear band crossings that could be missed. Additionally, in situ alkali-metal doping ofmore »« less

Dimensional crossover and symmetry transformation of charge density waves in VSe 2

Journal Article Chen, P. ; Chan, Y. -H. ; Liu, R. -Y. ; ... - Physical Review. B

Collective phenomena in solids can be sensitive to the dimensionality of the system; a case of special interest is VSe₂, which shows a (√7×√3) charge density wave (CDW) in the single layer with threefold symmetry in the normal phase spontaneously broken, in contrast to the (4×4) in-plane CDW in the bulk. Angle-resolved photoemission spectroscopy (ARPES) from VSe₂ ranging from a single layer to the bulk reveals the evolution of the electronic structure including the Fermi surface contours and the CDW gap. At a thickness of two layers, the ARPES maps are already nearly bulklike, but the transition temperature T_C formore »« less

Quantum anomalous Hall insulator phase in asymmetrically functionalized germanene

Journal Article Hsu, Chia-Hsiu ; Fang, Yimei ; Wu, Shunqing ; ... - Physical Review B

Here, using first-principles computations, we discuss topological properties of germanene in buckled as well as planar honeycombs with asymmetric passivation via hydrogen and nitrogen (GeHN) atoms. GeHN in the planar structure is found to harbor a quantum anomalous Hall (QAH) insulator phase. Our analysis indicates that the buckled GeHN also possesses a QAH phase under tensile strain. We computed the associated Chern numbers and edge states to confirm the presence of the QAH state. In particular, chiral edge bands connecting conduction and valence bands were found at the edges of a planar zigzag GeHN nanoribbon. By considering a range ofmore »« less

Integrated Solar-Driven Device with a Front Surface Semitransparent Catalysts for Unassisted CO₂ Reduction

Journal Article Cheng, Wen‐Hui ; Richter, Matthias H. ; Müller, Ralph ; ... - Advanced Energy Materials

Abstract Monolithic integrated photovoltaic‐driven electrochemical (PV‐EC) artificial photosynthesis is reported for unassisted CO ₂ reduction. The PV‐EC structures employ triple junction photoelectrodes with a front mounted semitransparent catalyst layer as a photocathode. The catalyst layer is comprised of an array of microscale triangular metallic prisms that redirect incoming light toward open areas of the photoelectrode to reduce shadow losses. Full wave electromagnetic simulations of the prism array (PA) structure guide optimization of geometries and length scales. An integrated device is constructed with Ag catalyst prisms covering 35% of the surface area. The experimental device has close to 80% of themore »« less

In this paper we study the effect of structure on the electronic and magnetic properties of mono- and bilayer VSe₂ films grown using molecular beam epitaxy. VSe₂ has recently attracted much attention due to reports of emergent ferromagnetism in the two-dimensional (2D) limit. To understand this compound, high-quality 1more »« less
