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…
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…
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…
