\emph{Ab initio} derivation of the crystal field parameters for lanthanide ions: The f case
Dumitru-Claudiu Sergentu, Gwenhaël Duplaix-Rata, Ionel Humelnicu +2
The crystal field theory as explained by Abragam and Bleaney in their landmark 1970 book on transition-ion electron paramagnetic resonance remains a cornerstone in the development…
Electronic and Thermoelectric Properties of Molecular Junctions Incorporating Organometallic Complexes: Implications for Thermoelectric Energy Conversion
Joseane Santos Almeida, Sergio González Casal, Hassan Al Sabea +15
The electronic and thermoelectric properties of molecular junctions formed from iron and ruthenium metal-acetylide were studied using complementary experimental techniques and quan…
Roadmap for electronic structure, anharmonicity, and electron-phonon calculations in locally disordered inorganic and hybrid halide perovskites
Marios Zacharias, George Volonakis, Laurent Pedesseau +3
The role of data in modern materials science becomes more valuable and accurate when effects such as electron-phonon coupling and anharmonicity are included, providing a more reali…
Electron-phonon couplings in polymorphous crystals
Marios Zacharias, George Volonakis, Laurent Pedesseau +3
Positional polymorphism in solids refers to locally disordered unit cells that, on average, reproduce the high-symmetry structures observed in diffraction experiments. Standard the…
Empirical approaches to Fröhlich excitonic polarons in polar semiconductors
Jacky Even, Simon Thebaud, Aseem Rajan Kshirsagar +4
The excitonic correlation between electron and hole and these carriers' interactions with underlying crystal lattice govern the opto-electronic response of semiconductors. The latt…
Two-dimensional perovskites with maximum symmetry enable exciton diffusion length exceeding 2 micrometers
Jin Hou, Jared Fletcher, Siedah J. Hall +15
Realizing semiconductors with high symmetry of their crystallographic structures has been a virtue of inorganic materials and has resulted in novel physical behaviors. In contrast,…
