Electronic charge densities for ZnS in the wurtzite and zincblende structures [PDF]
Journal of Physics C: Solid State Physics, 1973 Using the Empirical Pseudopotential Method electronic charge densities are calculated as a function of position in the unit cell for ZnS in a zincblende and ideal wurtzite structure. A comparison of the charge densities reveals the presence of a net polarization in the ideal wurtzite structure.

Pseudopotential Calculations of Electronic Charge Densities in Seven Semiconductors [PDF]
Physical Review B, 1971 Electronic charge densities are calculated as a function of position in the unit cell for seven diamond and zinc-blende semiconductors using wave functions derived from pseudopotential band-structure calculations. Detailed plots of the charge density are presented in the (110) plane for each valence band of Ge, GaAs, and ZnSe and for the sum of the ...

Thermodynamic behavior of correlated electron-hole fluids in van der Waals heterostructures
Nature Communications, 2023 Coupled two-dimensional electron-hole bilayers provide a unique platform to study strongly correlated Bose-Fermi mixtures in condensed matter. Electrons and holes in spatially separated layers can bind to form interlayer excitons, composite Bosons ...

Accuracy of charge densities in electronic structure calculations
The Journal of Chemical PhysicsAccurate charge densities are essential for reliable electronic structure calculations because they significantly impact predictions of various chemical properties and, in particular, according to the Hellmann–Feynman theorem, atomic forces. This study examines the accuracy of charge densities obtained from different density functional theory (DFT ...
