We report direct measurements via angle-resolved photoemission spectroscopy (ARPES) of the electronic dispersion of single-layer (SL) CoO2. The Fermi contour consists of a large hole pocket centered at the Γ‾ point. To interpret the ARPES results, we use density functional theory (DFT) in combination with the multi-orbital Gutzwiller Approximation (DFT+GA), basing our calculations on crystalline structure parameters derived from x-ray photoelectron diffraction and low-energy electron…

Fermi surface evolution and Luttinger theorem in Na(x)CoO2: a systematic photoemission study.

TLDR
The e'(g) band and the associated small Fermi surface pockets near the K points predicted by band calculations are found to sink below the Fermu energy in a manner almost independent of the doping and temperature.

Epitaxial growth of single-orientation high-quality MoS2 monolayers

We present a study on the growth and characterization of high-quality single-layer MoS2 with a single orientation, i.e. without the presence of mirror domains. This single orientation of the MoS2

Electronic Structure and Enhanced Charge-Density Wave Order of Monolayer VSe2.

TLDR
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.

Complete d-Band Dispersion and the Mobile Fermion Scale in NaxCoO2

We utilize fine-tuned polarization selection coupled with excitation-energy variation of photoelec-tron signal to image the complete d -band dispersion relation in sodium cobaltates. A hybridization

Au(111): A theoretical study of the surface reconstruction and the surface electronic structure.

TLDR
The surface band structure of the Au(111) surface along high-symmetry lines in the surface Brillouin zone, with the top layer occupying the fcc, hcp, and bridge sites is calculated and it is found that the surface electronic structure is almost independent of the position of the top layers.

Theoretical prediction of superconductivity in monolayer CoO2.

TLDR
The monolayer CoO2 possesses phonon-mediated superconductivity at 25-28 K owing to its intermediate to strong electron-phonon coupling (EPC), making this compound one of the highest-temperature superconductors among the existing 2D materials.

Fermi surface and quasiparticle dynamics of Na0.7CoO2 investigated by angle-resolved photoemission spectroscopy.

TLDR
Unusually small single-particle hopping and unconventional quasiparticle dynamics may have implications for understanding the phase of matter realized in this new class of a strongly interacting quantum system.

Charge ordering, commensurability, and metallicity in the phase diagram of the layered NaxCoO2.

TLDR
The phase diagram of nonhydrated NaxCoO2 has been determined by changing the Na content x using a series of chemical reactions and the unusual properties of the state at 1/2 (including particle-hole symmetry at low T and enhanced thermal conductivity) are described.

Interface controlled oxidation states in layered cobalt oxide nanoislands on gold.

TLDR
It is revealed that conversion from Co(2+) to Co(3+) can occur by a facile incorporation of oxygen at the interface between the nanoisland and gold, changing the islands from a Co-O bilayer to an O-Co-O trilayer.
