Probing Lithium Ion Transport at Individual Interfaces
Kartik Venkatraman, Yongqiang Cheng, Alexandra Moy +6
Ion transport across solid solid interfaces is often slower than through the bulk of a material, impeding the charge and discharge rate of batteries. Designing highly conductive in…
Dynamic crystallography reveals spontaneous anisotropy in cubic GeTe
Simon A. J. Kimber, Jiayong Zhang, Charles H. Liang +10
Cubic energy materials such as thermoelectrics or hybrid perovskite materials are often understood to be highly disordered. In GeTe and related IV-VI compounds, this is thought to…
Gapless Dirac magnons in CrCl
John A. Schneeloch, Yu Tao, Yongqiang Cheng +4
Bosonic Dirac materials are testbeds for dissipationless spin-based electronics. In the quasi two-dimensional honeycomb lattice of CrX (X=Cl, Br, I), Dirac magnons have been…
Reentrance of spin-driven ferroelectricity through rotational tunneling of ammonium
Yan Wu, Lei Ding, Na Su +9
Quantum effects fundamentally engender exotic physical phenomena in macroscopic systems, which advance next-generation technological applications. Rotational tunneling that represe…
Proton polarons in HxWO3 by synchrotron photoemission and DFT modelling
Emanuel Billeter, Andrea Sterzi, Olga Sambalova +6
The measurement of hydrogen induced changes on the electronic structure of transition metal oxides by X-ray photoelectron spectroscopy is a challenging endeavor, since the origin o…
Study of anharmonicity in Zirconium Hydrides using inelastic neutron scattering and ab-initio computer modeling
Jiayong Zhang, Yongqiang Cheng, Alexander I. Kolesnikov +3
The anharmonic phenomena in Zirconium Hydrides and Deuterides, including ε-ZrH2, γ-ZrH, and γ-ZrD, have been investigated from aspects of inelastic neutron scattering (INS) and lat…
In situ quasi-elastic neutron scattering study on the water dynamics and reaction mechanisms in alkali-activated slags
Kai Gong, Yongqiang Cheng, Luke L. Daemen +1
In this study, in situ quasi-elastic neutron scattering (QENS) has been employed to probe the water dynamics and reaction mechanisms occurring during the formation of NaOH- and Na2…
