Imaging the electron charge density in monolayer MoS2 at the Ångstrom scale [PDF]
Nature Communications, 2023 Four-dimensional scanning transmission electron microscopy (4D-STEM) has recently gained widespread attention for its ability to image atomic electric fields with sub-Ångstrom spatial resolution.

Nuclear Charge Density Distributions from Elastic Electron Scattering Data [PDF]
Nuclear Physics A, 1994 The model independent procedure of extracting charge density distributions from elastic electron scattering data is investigated. The charge density distributions are expanded on an orthonormal basis and the parameters of the expansions are fixed by the ...

Ultrafast charge migration in ionized iodo-alkyne chain I(CC)nH+
AIP Advances, 2023 We report ultrafast charge migration in ionized iodo-alkyne chain I(CC)nH+ for n = 1, 2, …, 5. The dynamics of electron density become more complicated with the increasing length of the molecular chain.

Electronic charge density in PbTe [PDF]
Solid State Communications, 1972 Abstract The electronic charge density for PbTe is computed as a function of position in the unit cell and is displayed on two different planes. A rough estimate of the charge about each atom is made. The charge density for the top valence and bottom conduction bands are given for the L point of the Brillouin zone. The influence of the L-point charge

Theoretical investigation of four-body interaction in the one-dimensional extended Hubbard model
Results in Physics, 2022 In the weak-coupling regime, we analytically investigate phase diagram of a one-dimensional half-filled extended Hubbard model with nearest neighboring four-electron interaction (Q), in addition to the usual two-electron couplings (U,V>0). The additional

Electronic charge density of aluminum [PDF]
Solid State Communications, 1973 Abstract The valence electronic charge density is calculated for aluminum from wave-functions obtained via Ashcroft's pseudopotential. A contour plot of the charge density is presented in the (100) plane. The Fourier transform of the charge density is used to calculate the atomic form factors which are compared with experimental X-ray form factors ...

A potential all-electronic route to the charge-density-wave phase in monolayer vanadium diselenide
Communications Physics, 2021 Charge density waves are periodic modulations of the electron density which occur at low temperatures in many transition metal dichalcogenide monolayers, though the underlying mechanism is still a matter of debate.

Charge density waves and degenerate modes in exfoliated monolayer 2H-TaS2
IUCrJ, 2020 Charge density waves spontaneously breaking lattice symmetry through periodic lattice distortion, and electron–electron and electron–phonon interactions, can lead to a new type of electronic band structure.

Discovery of conjoined charge density waves in the kagome superconductor CsV3Sb5
Nature Communications, 2022 The nature of unconventional charge density wave in kagome metals is currently under intense debate. Here the authors report the coexistence of the 2 × 2 × 1 charge density wave in the kagome sublattice and the Sb 5p-electron assisted 2 × 2 × 2 charge ...
