Crystal Field Theory - Tetrahedral and Square Planar Complexes02:46

Crystal Field Theory - Tetrahedral and Square Planar Complexes

41.4K
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,...

Strain and Elastic Modulus

3.5K
The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or geometry under tensile, volume (also known as bulk), or shear stress, respectively, and is a dimensionless quantity. The strain experienced by a body under tensile or compressive stress is called tensile or compressive strain, respectively. In contrast, the strain experienced under bulk stress and shear stress is known as volume and shear...

Elastic Strain Energy for Normal Stresses

134
Strain energy quantifies the energy stored within a material due to deformation under loading conditions, a fundamental concept in materials science and engineering. The strain energy can be modeled when a material is subjected to axial loading with uniformly distributed stress. In this scenario, the stress experienced by the material is the internal force divided by the cross-sectional area, and the strain induced is directly proportional to this stress through the modulus of elasticity.

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Elastic Strain Energy for Shearing Stresses

158
As discussed in previous lessons, strain energy in a material is the energy stored when it is elastically deformed, a concept crucial in materials science and mechanical engineering. This energy results from the internal work done against the cohesive forces within the material. When a material undergoes shearing stress and corresponding shearing strain, the strain energy density, which is the energy stored per unit volume, is calculated. Within the elastic limit, where the stress is...

Strain-Energy Density01:20

Strain-Energy Density

358
Understanding the strain energy density in materials under axial load is crucial for evaluating their mechanical behavior and durability. When a rod is subjected to such a load, it elongates and stores energy, known as strain energy, as potential energy within the material. This energy is measured in terms of energy per unit volume.
In the elastic region of a material, the relationship between the stress and the strain is linear and follows Hooke's Law. The strain energy density in this...

Area of Science:

  • Materials Science
  • Solid State Physics
  • Dielectric Materials

Background:

  • Electrostriction is the strain induced in dielectric materials by an electric field.
  • Oxygen-defective metal oxides, particularly acceptor-doped ceria, show significant electrostriction.
  • This effect in ceria is non-classical, linked to defect-induced polarization and lattice distortion.

Purpose of the Study:

  • To investigate the impact of mismatch strain on electrostriction in epitaxial gadolinium-doped ceria (GDC) thin films.
  • To explore how varying compressive and tensile strain influences the electromechanical response.
  • To understand the underlying mechanisms for enhanced electrostriction in GDC films.

Main Methods:

  • Epitaxial growth of GDC thin films on various single-crystal substrates.
  • Application of controlled strain (compressive and tensile) via substrate mismatch.
  • Characterization of electromechanical response, lattice strain, and defect structures.

Main Results:

  • Electrostriction coefficients were significantly enhanced in GDC films under in-plane compression.
  • A maximum electrostriction coefficient (M11) of approximately 3.6·10^-15 m^2V^-2 was achieved.
  • High compressive stress (>3 GPa) and positive tetragonality were observed in the films with enhanced electrostriction.

Conclusions:

  • Mismatch strain is a critical factor in tuning the electrostrictive properties of GDC thin films.
  • Anisotropic lattice distortions and defect engineering contribute to the enhanced non-classical electrostriction.
  • This work provides a pathway for optimizing electromechanical performance in dielectric oxides through strain engineering.
