Comment on "Origin of correlated isolated flat bands in copper-substituted lead phosphate apatite"
Michael W. Swift, John L. Lyons
In this comment on "Origin of correlated isolated flat bands in copper-substituted lead phosphate apatite" (arXiv:2307.16892 [cond-mat.supr-con]), we discuss the flat half-occupied…
Lone-Pair Stereochemistry Induces Ferroelectric Distortion and the Rashba Effect in Inorganic Halide Perovskites
Michael W. Swift, John L. Lyons
The lone-pair s states of germanium, tin, and lead underlie many of the unconventional properties of the inorganic metal halide perovskites. Dynamic stereochemical expression of th…
Dark and Bright Excitons in Halide Perovskite Nanoplatelets
Moritz Gramlich, Michael W. Swift, Carola Lampe +5
Semiconductor nanoplatelets (NPLs), with their large exciton binding energy, narrow photoluminescence (PL), and absence of dielectric screening for photons emitted normal to the NP…
Understanding Carbon Contamination in Proton Conducting Oxides
Andrew J. E. Rowberg, Michael W. Swift, Chris G. Van de Walle
Carbon contamination is a significant concern for proton-conducting oxides in the cerate and zirconate family, particularly for BaCeO. Here, we use first-principles calculation…
Wavelet Scattering Networks for Atomistic Systems with Extrapolation of Material Properties
Paul Sinz, Michael W. Swift, Xavier Brumwell +4
The dream of machine learning in materials science is for a model to learn the underlying physics of an atomic system, allowing it to move beyond interpolation of the training set…
First-principles prediction of potentials and space-charge layers in all-solid-state batteries
Michael W. Swift, Yue Qi
As all-solid-state batteries (SSBs) develop as an alternative to traditional cells, a thorough theoretical understanding of driving forces behind battery operation is needed. We pr…
SrIrOF: Topochemical conversion of a relativistic Mott state into a spin-orbit driven band insulator
Christi Peterson, Michael W. Swift, Zach Porter +9
The topochemical transformation of single crystals of SrIrO into SrIrOF is reported via fluorine insertion. Characterization of the newly formed SrI…
Posner molecules: From atomic structure to nuclear spins
Michael W. Swift, Chris G. Van de Walle, Matthew P. A. Fisher
We investigate "Posner molecules", calcium phosphate clusters with chemical formula Ca(PO). Originally identified in hydroxyapatite, Posner molecules have also been obs…
Electron doping in : collapse of band gap and magnetic order
Michael W. Swift, Zach Porter, Stephen D. Wilson +1
The electron-doping-driven collapse of the charge gap and staggered magnetization of the spin-orbit-assisted Mott insulator SrIrO is explored via first-principles…
Linear hyperfine tuning of donor spins in silicon using hydrostatic strain
John Mansir, Pierandrea Conti, Zaiping Zeng +8
We experimentally study the coupling of Group V donor spins in silicon to mechanical strain, and measure strain-induced frequency shifts which are linear in strain, in contrast to…
Conditions for resistivity from electron-electron scattering
Michael Swift, Chris G. Van de Walle
Many complex oxides (including titanates, nickelates and cuprates) show a regime in which resistivity follows a power law in temperature (). By analogy to a similar p…
Hydrogen Diffusion and Stabilization in Single-crystal VO2 Micro/nanobeams by Direct Atomic Hydrogenation
Jian Lin, Heng Ji, Michael W. Swift +6
We report measurements of the diffusion of atomic hydrogen in single crystalline VO2 micro/nanobeams by direct exposure to atomic hydrogen, without catalyst. The atomic hydrogen is…
In situ diffraction study of catalytic hydrogenation of VO2: Stable phases and origins of metallicity
Yaroslav Filinchuk, Nikolay A. Tumanov, Voraksmy Ban +5
Controlling electronic population through chemical doping is one way to tip the balance between competing phases in materials with strong electronic correlations. Vanadium dioxide…
