The Hall Effect01:30

The Hall Effect

5.2K
Edwin H. Hall, in the year 1879, devised an experiment that could be used to identify the polarity of the predominant charge carriers in a conducting material. From a historical perspective, this experiment was the first to demonstrate that the charge carriers in most metals are negative.

Imperfections in Crystal Structure: Stoichiometric Point Defects

147
Schottky defects arise when some lattice points in a crystal, such as those in NaCl, remain unoccupied, creating lattice vacancies without disturbing the overall electrical neutrality of the crystal. This defect is common in ionic crystals where the positive and negative ions are similar in size, as seen in sodium chloride and cesium chloride. The presence of Schottky defects enables the crystal to conduct electricity to a small extent through an ionic mechanism. Electric fields cause nearby...

π Electron Effects on Chemical Shift: Overview

1.5K
An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0,...

π Electron Effects on Chemical Shift: Aromatic and Antiaromatic Compounds

1.7K
In aromatic compounds, such as benzene, the circulation of (4n + 2) π-electrons sets up a diamagnetic or diatropic ring current around the perimeter of the molecule. This current induces a magnetic field that opposes the external field inside the ring and reinforces it on the outside. The protons in benzene are deshielded and exhibit high chemical shifts in the range 6.5–8.5 ppm. The shielding effect at the center of the ring is evident in complex aromatic molecules, such as...

Trends in Lattice Energy: Ion Size and Charge

23.4K
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:

Valence Bond Theory02:42

Valence Bond Theory

8.9K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Summary

Disorder impacts the quantum Hall effect in trilayer graphene (TLG). Rhombohedral-stacked TLG shows more robust Hall plateaus against disorder than Bernal-stacked TLG due to stronger quasiparticle immunity.

Area of Science:

  • Condensed Matter Physics
  • Materials Science

Background:

  • The integer quantum Hall effect (IQHE) is a key phenomenon in 2D electron systems.
  • Trilayer graphene (TLG) offers unique electronic properties due to its layered structure.
  • Understanding disorder effects is crucial for practical applications of graphene-based electronics.

Purpose of the Study:

  • To numerically investigate the impact of disorder on the IQHE in both Bernal (ABA) and rhombohedral (ABC) stacked TLG.
  • To compare the stability of quantum Hall plateaus in ABA-TLG versus ABC-TLG under varying disorder strengths.
  • To elucidate the role of chiral quasiparticles in determining disorder resilience.

Main Methods:

  • Numerical investigation using the Kubo formula.
  • Simulation of disorder effects on quantum Hall plateaus.
  • Analysis of longitudinal conductance minima.

Main Results:

  • Both ABA-TLG and ABC-TLG exhibit abnormal quantized Hall plateaus at the band center and normal ones at band edges in clean samples.
  • Disorder obscures Hall plateaus, with higher plateaus disappearing first.
  • ABA-TLG's Hall plateaus are more susceptible to disorder than ABC-TLG's.
  • Longitudinal conductance minima narrow with disorder, with ABC-TLG showing greater stability.

Conclusions:

  • ABC-stacked TLG demonstrates superior robustness against disorder compared to ABA-stacked TLG.
  • The enhanced stability in ABC-TLG is attributed to the disorder immunity of its l=3 chiral quasiparticles with cubic dispersion.
  • Findings suggest potential advantages of ABC-TLG for applications requiring high electronic stability in disordered environments.
