Accurate and efficient prediction of the band gaps and optical spectra of chalcopyrite semiconductors from a non-empirical range-separated dielectric-dependent hybrid: Comparison with many-body perturbation theory
Arghya Ghosh, Subrata Jana, Dimple Rani +3
The accurate prediction of electronic and optical properties in chalcopyrite semiconductors has been a persistent challenge for density functional theory (DFT) based approaches. Ad…
Adiabatic connection interaction strength interpolation method made accurate for the uniform electron gas
Lucian A. Constantin, Subrata Jana, Szymon Śmiga +1
The adiabatic connection interaction strength interpolation (ISI)-like method provides a high-level expression for the correlation energy, being in principle exact in the weak-inte…
Efficient and improved prediction of the band offsets at semiconductor heterojunctions from meta-GGA density functionals
Arghya Ghosh, Subrata Jana, Tomáš Rauch +6
Accurate theoretical prediction of the band offsets at interfaces of semiconductor heterostructures can often be quite challenging. Although density functional theory has been reas…
Excited-State Density-Functional Theory Revisited: on the Uniqueness, Existence, and Construction of the Density-to-Potential Mapping
Prasanjit Samal, Subrata Jana, Sourabh S. Chauhan
The generalized constrained search formalism is used to address the issues concerning density-to-potential mapping for excited states in time-independent density-functional theory.…
