Synthetic control over polymorph formation in the d-band semiconductor system FeS
KeYuan Ma, Robin Lefèvre, Qingtian Li +4
Pyrite, also known as fool's gold is the thermodynamic stable polymorph of FeS. It is widely considered as a promising d-band semiconductor for various applications due to its…
Coulombically-stabilized oxygen hole polarons enable fully reversible oxygen redox
Iwnetim I. Abate, C. Das Pemmaraju, Se Young Kim +10
Stabilizing high-valent redox couples and exotic electronic states necessitate an understanding of the stabilization mechanism. In oxides, whether they are being considered for ene…
Disparate exciton-phonon couplings for zone center and boundary phonons in solid-state graphite
Xuefei Feng, Shawn Sallis, Yu-Cheng Shao +8
The exciton-phonon coupling in highly oriented pyrolytic graphite is studied using resonant inelastic X-ray scattering (RIXS) spectroscopy. With ~ 70 meV energy resolution, multipl…
Fingerprint oxygen redox reactions in batteries through high-efficiency mapping of resonant inelastic X-ray scattering (mRIXS)
Jinpeng Wu, Qinghao Li, Shawn Sallis +6
Realizing reversible reduction-oxidation (Redox) reactions of lattice oxygen in batteries is a promising way to improve the energy and power density. However, conventional oxygen a…
High Reversibility of Lattice Oxygen Redox in Na-ion and Li-ion Batteries Quantified by Direct Bulk Probes of both Anionic and Cationic Redox Reactions
Kehua Dai, Jinpeng Wu, Zengqing Zhuo +17
The reversibility and cyclability of anionic redox in battery electrodes hold the key to its practical employments. Here, through mapping of resonant inelastic X-ray scattering (mR…
Spectroscopic Signature of Oxidized Oxygen States in Peroxides
Zengqing Zhuo, Chaitanya Das Pemmaraju, John Vinson +12
