Effect of disorder and doping on electronic structure and diffusion properties of LiVO
Mohammad Babar, Hasnain Hafiz, Zeeshan Ahmad +3
VO in its phase (LiVO) with excess lithium is a potential alternative to the graphite anode for lithium-ion batteries at low temperature and fast…
Redox oscillations in 18650-type lithium-ion cell revealed by in operando Compton scattering imaging
Kosuke Suzuki, Shunta Suzuki, Yuji Otsuka +12
Compton scattering imaging using high-energy synchrotron x-rays allows the visualization of the spatio-temporal lithiation state in lithium-ion batteries probed in-operando. Here,…
Identification of ferrimagnetic orbitals preventing spinel degradation by charge ordering in LiMnO
Hasnain Hafiz, Kosuke Suzuki, Bernardo Barbiellini +10
Spinel LiMnO is a key cathode material that is used extensively in commercial Li-ion batteries. A challenge with this material has been that the capacity of the battery…
Many-body effects in porphyrin-like transition metal complexes embedded in graphene
Andrew Allerdt, Hasnain Hafiz, Bernardo Barbiellini +2
We introduce a new computational method to study porphyrin-like transition metal complexes, bridging density functional theory and exact many-body techniques, such as the density m…
Engineering Three-Dimensional (3D) Out-of-Plane Graphene Edge Sites for Highly-Selective Two-Electron Oxygen Reduction Electrocatalysis
Daniel San Roman, Dilip Krishnamurthy, Raghav Garg +4
Selective two-electron oxygen reduction reaction (ORR) offers a promising route for hydrogen peroxide synthesis, and defective sp2 carbon-based materials are attractive, low-cost e…
Fermi Arcs vs. Fermi Pockets in Electron-doped Perovskite Iridates
Junfeng He, H. Hafiz, Thomas R. Mion +11
We report on an angle resolved photoemission (ARPES) study of bulk electron-doped perovskite iridate, (Sr1-xLax)3Ir2O7. Fermi surface pockets are observed with a total electron cou…
