Thinning crystalline materials to two dimensions (2D) creates a rich playground for electronic phases, including charge, spin, superconducting, and topological order. Bulk materials hosting charge density waves (CDWs), when reduced to ultrathin films, have shown CDW enhancement and tunability. However, charge order confined to only 2D remains elusive. Here we report a distinct charge ordered state emerging in the monolayer limit of 1T-VSe2. Systematic scanning tunneling microscopy experiments…

Topical review: recent progress of charge density waves in 2D transition metal dichalcogenide-based heterojunctions and their applications
The interplay between CDW patterns and the related unique electronic phenomena (superconductivity, spin, and Mottness) is elucidated and various manipulation methods such as doping, applying strain, local voltage pulse to induce the CDW change are discussed.
A full gap above the Fermi level: the charge density wave of monolayer VS2
It is shown that VS2 realizes a CDW which stands out of this standard model, and x-ray magnetic circular dichroism reveals the absence of net magnetization in this phase, pointing to coexisting charge and spin density waves in the ground state.


Electronic Structure and Enhanced Charge-Density Wave Order of Monolayer VSe2.
This study uses angle-resolved photoemission to investigate the electronic structure of monolayer VSe2 grown on bilayer graphene/SiC and shows that pronounced energy gaps develop over the entire Fermi surface with decreasing temperature below Tc = 140 ± 5 K, concomitant with the emergence of charge-order superstructures evident in low-energy electron diffraction.
Charge Density Wave State Suppresses Ferromagnetic Ordering in VSe2 Monolayers
Ferromagnetic ordering of monolayer vanadium dichalcogenides (VSe2 and VS2) has been predicted by density functional theory (DFT), and suggestive experimental evidence for magnetic ordering in VSe2
Unique Gap Structure and Symmetry of the Charge Density Wave in Single-Layer VSe_{2}.
This robust CDW with an exotic broken symmetry as the ground state is explained via a first-principles analysis and illustrates a unique CDW phenomenon in the two-dimensional limit.
Emergence of a Metal-Insulator Transition and High-Temperature Charge-Density Waves in VSe2 at the Monolayer Limit.
By reducing the material thickness and forming a heterointerface, two types of charge-ordering transitions in monolayer VSe2 on graphene substrates are found and an unexpected metal-insulator transition at 135 K that is driven by lattice distortions is confirmed.
Atomic-scale strain manipulation of a charge density wave
The microscopic mechanism of a CDW formation is unveiled in 2H-NbSe2, and can serve as a general tool compatible with a range of spectroscopic techniques to engineer electronic states in any material where local strain or lattice symmetry breaking plays a role.
Strain Engineering a 4a×√3a Charge Density Wave Phase in Transition Metal Dichalcogenide 1T-VSe2.
A rectangular charge density wave (CDW) phase in strained 1T-VSe2 thin films synthesized by molecular beam epitaxy on c-sapphire substrates is reported, and the unconventional structure becomes preferred in the presence of strain, in agreement with experimental findings.
Structure and control of charge density waves in two-dimensional 1T-TaS2
It is demonstrated that the intrinsic properties of atomically thin flakes are preserved by encapsulation with hexagonal boron nitride in inert atmosphere and this facile assembly method is used together with transmission electron microscopy and transport measurements to probe the nature of the 2D state and show that its conductance is dominated by discommensurations.
Strongly enhanced charge-density-wave order in monolayer NbSe2.
A combined optical and electrical transport study on the many-body collective-order phase diagram of NbSe2 down to a thickness of one monolayer opens up a new window for search and control of collective phases of two-dimensional matter, as well as expanding the functionalities of these materials for electronic applications.
Pseudogap, Fermi arc, and Peierls-insulating phase induced by 3D–2D crossover in monolayer VSe2
AbstractOne of important challenges in condensed-matter physics is to realize new quantum states of matter by manipulating the dimensionality of materials, as represented by the discovery of
Ultrafast Triggering of Insulator-Metal Transition in Two-Dimensional VSe2.
The interplay of electronic and lattice degrees of freedom that underpin these phases in single-layer VSe2 are investigated using ultrafast pump-probe photoemission spectroscopy and suggest that the phase transition is driven by electron-lattice interactions rather than by Mott-like electronic effects.
