Dielectric constant of gray Tin: A first-principles study

  title={Dielectric constant of gray Tin: A first-principles study},
  author={Jinsong Duan},
α -Sn (gray tin) is a group-IV, zero-gap semiconductor with potential use in infrared detectors, necessitating a clear understanding of its dielectric properties. We report the first-principles calculations of the band structure and dielectric function of α -Sn using density functional theory, emphasizing the effects of strain, spin-orbit interaction, and pseudo-potentials on the electronic and optical properties of α -Sn in the infrared region (photon energy < 1eV). In α -Sn, spin-orbit coupling…

Spin dynamics in the topological elemental gray Tin from first principles perspective
Gray Tin is attracting much more interest as a topological quantum material, which has a precisely controlled composition and can be a material for spintronic devices. However, the spin dynamics in

Nonlocality and many-body effects in the optical properties of semiconductors.
Numerical calculations of the frequency-dependent dielectric function for different gauges of the electromagnetic field in the optical transition operator are reported and results for optical spectra where the many-body quasiparticle effect is included beyond the scissors-operator approximation are presented.
Role of Polar Phonons in the Photo Excited State of Metal Halide Perovskites
Calculating the polarization in time from finite temperature molecular dynamics, it is shown that at room temperature this does not change and is argued in favor of the formation of polarons.

This work shows how the strain deforms the constant energy surface in k space and compares the subband structure calculated with and without the split-off bands, demonstrating that the spin-orbit coupling has significant effects on the band structure especially for highly strained quantum wells and cannot be ignored.
