The nature of dynamic local order in CHNHPbI and CHNHPbBr
Nicholas Weadock, Tyler Sterling, Julian Vigil +12
Hybrid lead halide perovskites (LHPs) are a class of semiconductor with novel properties that are distinctively governed by structural fluctuations. Diffraction experiments sensiti…
Structural changes induced by electric currents in a single crystal of PrCuO
Susmita Roy, Feng Ye, Zachary Morgan +7
We demonstrate a novel approach to the structural and electronic property modification of perovskites, focusing on PrCuO, an undoped parent compound of a class of electron-…
Occupational Disorder as the Origin of Flattening of the Acoustic Phonon Branches in the Clathrate BaGaGe
Susmita Roy, Tyler C. Sterling, Daniel Parshall +4
In the search for high-performance thermoelectrics, materials such as clathrates have drawn attention due to having both glass-like low phonon thermal conductivity and crystal-like…
Electron-momentum dependence of electron-phonon coupling underlies dramatic phonon renormalization in YNiBC
Philipp Kurzhals, Geoffroy Kremer, Thomas Jaouen +12
Electron-phonon coupling, i.e., the scattering of lattice vibrations by electrons and vice versa, is ubiquitous in solids and can lead to emergent ground states such as superconduc…
Effect of the electronic charge gap on LO bond-stretching phonons in undoped LaCuO calculated using LDA+U
Tyler C. Sterling, Dmitry Reznik
Typical density-functional theory calculations that wrongly predict undoped cuprates to be metallic also predict Cu-O half- and full-breathing phonon energies that are significantl…
Spinons and damped phonons in spin-1/2 quantum-liquid BaIrO observed by Raman scattering
Aaron Sokolik, Sami Hakani, Susmita Roy +5
In spin-1/2 Mott insulators, non-magnetic quantum liquid phases are often argued to arise when the system shows no magnetic ordering, but identifying positive signatures of these p…
