Title: Persistent Charge-Density-Wave Order in Single-Layer TaSe ₂

Abstract

We present the electronic characterization of single-layer 1H-TaSe₂ grown by molecular beam epitaxy using a combined angle-resolved photoemission spectroscopy, scanning tunneling microscopy/spectroscopy, and density functional theory calculations. We demonstrate that 3 × 3 charge-density-wave (CDW) order persists despite distinct changes in the low energy electronic structure highlighted by the reduction in the number of bands crossing the Fermi energy and the corresponding modification of Fermi surface topology. Enhanced spin-orbit coupling and lattice distortion in the single-layer play a crucial role in the formation of CDW order. Our findings provide a deeper understanding of the nature of CDW order in the two-dimensional limit.

Optically induced changes in the band structure of the Weyl charge-density-wave compound (TaSe₄)₂I

Journal Article Crepaldi, A. ; Puppin, M. ; Gosálbez-Martínez, D. ; ... - JPhys Materials

Collective modes are responsible for the emergence of novel quantum phases in topological materials. In the quasi-one dimensional (1D) Weyl semimetal (TaSe₄)₂I, a charge density wave (CDW) opens band gaps at the Weyl points, thus turning the system into an axionic insulator. Melting the CDW would restore the Weyl phase, but 1D fluctuations extend the gapped regime far above the 3D transition temperature (T_CDW = 263 K), thus preventing the investigation of this topological phase transition with conventional spectroscopic methods. Here we use a non-equilibrium approach: we perturb the CDW phase by photoexcitation, and we monitor the dynamical evolution of the band structure by time- and angle-resolved photoelectron spectroscopy. We find that, upon optical excitation, electrons populate the linearly dispersing states at the Fermi level (E_F), and fill the CDW gap. The dynamics of both the charge carrier population and the band gap renormalization (BGR) show a fast component with a characteristic time scale of a few hundreds femtoseconds. However, the BGR also exhibits a second slow component on the µs time scale. The combination of an ultrafast response and of persistent changes in the spectral weight at Emore »« less

Scanning-probe-microscopy studies of superlattice structures and density-wave structures in 2H-NbSe[sub 2], 2H-TaSe[sub 2], and 2H-TaS[sub 2] induced by Fe doping

Journal Article Dai, Z ; Xue, Q ; Gong, Y ; ... - Physical Review, B: Condensed Matter; (United States)

The intercalation of Fe into the van der Waals gap in the 2H phase transition-metal dichalcogenides NbSe[sub 2], TaSe[sub 2], and TaS[sub 2] produces many interesting electronic, magnetic, and structural effects. The scanning tunneling microscope (STM) and atomic force microscope (AFM) prove to be very sensitive to these changes and we report a wide range of results as a function of Fe concentration. All three materials support similar 3[bold a][sub 0][times]3[bold a][sub 0] charge-density-wave (CDW) structures in the pure state at low temperatures. At low concentrations of Fe the CDW superlattice is still strong at 4.2 K and persists tomore »« less

Quantization of the band at the surface of charge density wave material 2H-TaSe₂

Journal Article Li, Man ; Xu, Nan ; Zhang, Jianfeng ; ... - Chinese Physics B

By using angle-resolved photoemission spectroscopy combined with the first-principles electronics atructure calculations, we report the quantum well states at the surface of a single crystal 2H-TaSe₂. We observed sub-bands at the three-dimensional Brillouin zone center forming the quantized states due to its highly dispersive nature and light effective mass along k_z direction. The quantized sub-bands shift upward towards E_F with the decrease of temperature across TCDW. The band shift could not be explained by two-dimensional Fermi-surface nesting-driven charge density waves(CDW), nor by purely strong electron-phonon coupling only. The CDW in 2H-TaSe₂ is likely related to the bands at higher bindingmore »« less

Characterization of collective ground states in single-layer NbSe₂

Journal Article Ugeda, Miguel M. ; Bradley, Aaron J. ; Zhang, Yi ; ... - Nature Physics

Layered transition metal dichalcogenides are ideal systems for exploring the effects of dimensionality on correlated electronic phases such as charge density wave (CDW) order and superconductivity. In bulk NbSe₂ a CDW sets in at T CDW = 33 K and superconductivity sets in at T_c = 7.2 K. Below T_c these electronic states coexist but their microscopic formation mechanisms remain controversial. Here we present an electronic characterization study of a single two-dimensional (2D) layer of NbSe₂ by means of low-temperature scanning tunnelling microscopy/spectroscopy (STM/STS), angle-resolved photoemission spectroscopy (ARPES), and electrical transport measurements. We demonstrate that 3 × 3 CDW ordermore »« less

Scanning tunneling microscopy of atoms and charge density waves in 1T-TaS/sub 2/, 1T-TaSe/sub 2/ and 1T-VSe/sub 2/

Technical Report Slough, G ; Giambattista, B ; Johnson, A ; ...

The layer structure dichalcogenide materials TaS/sub 2/ and TaSe/sub 2/ grow in several different phases depending on the coordination between the Ta and chalcogenide atoms and the number of three layer sandwiches per unit cell. The 1T phase has octahedral coordination between the Ta and chalcogenide atoms and has one three layer sandwich per unit cell. The high temperature Fermi surfaces (FSs) of the 1T phase Ta based materials exhibit a favorable nesting condition and undergo a charge-density-wave (CDW) transition at temperatures well above room temperature.
