Trends in Lattice Energy: Ion Size and Charge02:54

Trends in Lattice Energy: Ion Size and Charge

24.2K
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a measure of the strength of this attraction. The lattice energy (ΔHlattice) of an ionic compound is defined as the energy required to separate one mole of the solid into its component gaseous ions. For the ionic solid sodium chloride, the lattice energy is the enthalpy change of the process:

Current Density01:21

Current Density

4.3K
The total amount of current flowing through one unit value of a cross-sectional area is referred to as current density. If the current flow is uniform, the amount of current flowing through a conductor is the same at all points along the conductor, even if the conductor area varies. The current density consists of the local magnitude and direction of the charge flow, which varies from point to point. Current density is measured in amperes per meter square, and direction is defined as the net...

Crystal Field Theory - Tetrahedral and Square Planar Complexes

Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

Continuous Charge Distributions01:17

Continuous Charge Distributions

7.1K
Imagine a bucket of water. It contains many molecules, of the order of 1026 molecules. Thus, although it contains discrete elements (molecules) at the microscopic level, macroscopically, it can be considered continuous. Small volume elements of water, infinitesimal compared to the bulk of the bucket's volume, still contain many molecules. Under this framework, quantized matter is approximated as continuous for practical purposes.
The electric charge can also be subjected to an analogical...

Electrostatic Boundary Conditions in Dielectrics

1.4K
When an electric field passes from one homogeneous medium to another, crossing the boundary between the two mediums imparts a discontinuity in the electric field. This results in electrostatic boundary conditions that depend on the type of mediums the field propagates through.
Consider a case where both the mediums across a boundary are two different dielectric materials. Recall that the electric field and electric displacement are proportional and related through the material's...

Electric Field of Parallel Conducting Plates01:16

Electric Field of Parallel Conducting Plates

1.1K
Gauss' law relates the electric flux through a closed surface to the net charge enclosed by that surface. Gauss's law can be applied to find the electric field and the charge enclosed in a region depending on its charge distribution.
Consider a cross-section of a thin, infinite conducting plate having a positive charge. For such a large thin plate, as the thickness of the plate tends to zero, the positive charges lie on the plate's two large faces. Without an external electric...

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Solid State Chemistry

Background:

  • Superconductivity research aims to replicate cuprate behavior in new materials.
  • Infinite-layer nickelates have emerged as a promising class of superconductors.
  • Strong Coulomb interactions in nickelates suggest potential for symmetry-breaking orders.

Purpose of the Study:

  • To investigate the presence and characteristics of charge density waves (CDWs) in infinite-layer nickelates.
  • To understand the relationship between CDWs, orbital hybridization, and superconductivity in NdNiO2 films.

Main Methods:

  • Utilized Ni L3 resonant X-ray scattering to detect CDWs.
  • Employed spectroscopic studies to analyze orbital hybridization.
  • Investigated doped NdNiO2 films with varying Sr concentrations.

Main Results:

  • Observed CDWs in infinite-layer NdNiO2 films at a commensurate wavevector (0.333, 0).
  • CDWs were found to involve both Nd 5d and Ni 3d orbitals with significant out-of-plane dependence.
  • A strong correlation was identified between CDWs and Nd 5d-Ni 3d orbital hybridization.
  • CDWs vanished upon entering the superconducting state at 20% Sr doping.

Conclusions:

  • Demonstrated the existence of multiorbital CDWs in infinite-layer nickelates, differing from cuprates.
  • Established a link between CDWs, orbital hybridization, and the emergence of superconductivity.
  • Provided crucial insights into the low-energy physics of infinite-layer nickelates.
