The hybrid lead halide perovskite (LHP) family exhibits large structural fluctuations that contribute to the remarkable properties of LHP-based optoelectronic devices. In three-dimensional LHPs such as CH_{3}NH_{3}PbBr_{3}, the structural phase trans

Control over conductivity and carrier type (electrons and holes) defines semiconductors. A primary approach to target carrier concentrations involves introducing a small population of aliovalent impurity dopant atoms. In a combined synthetic and comp

Hybrid organic–inorganic perovskites (HOIPs) such as methylammonium lead iodide (MAPbI _3 ) are promising candidates for use in photovoltaic cells and other semiconductor applications, but their limited chemical stability poses obstacles to their w

A key component in calculations of exchange and correlation energies is the Coulomb operator, which requires the evaluation of two-electron integrals. For localized basis sets, these four-center integrals are most efficiently evaluated with the resol

We present a series of numerically tabulated atom-centered orbital (NAO) basis sets with valence-correlation consistency (VCC), termed NAO-VCC- n Z. Here the index ‘ n Z’ refers to the number of basis functions used for the valence shell with n =
