Implication

Randomized trial investigates how pressure affects electronic and optical properties of ZnTe, suggesting implications for ultraviolet applications.

Key Points

  • The study aims to explore the effects of pressure on various properties of zinc-blende ZnTe using advanced theoretical models.
  • Utilized density functional theory (DFT) and density functional perturbation theory (DFPT) for analysis.
  • Examined structural, electronic, optical, and vibrational properties under pressures from 0-20 GPa.
  • Analyzed electronic structure with the Perdew-Burke-Ernzerhof (PBE) and hybrid HSE06 functionals.
  • At ambient pressure, PBE underestimates the bandgap at 1.083 eV compared to HSE06's prediction of 2.63 eV.
  • Bandgap decreases with increasing pressure, transitioning from direct to indirect at 18 GPa.
  • Significant pressure-induced changes in optical spectra reveal enhanced reflectivity in the far-ultraviolet region.
