Structural and electronic transformations in TiO2 induced by electric current

Autor: Sterling, Tyler C., Ye, Feng, Jo, Seohyeon, Parulekar, Anish, Zhang, Yu, Cao, Gang, Raj, Rishi, Reznik, Dmitry

In-situ diffuse neutron scattering experiments revealed that when electric current is passed through single crystals of rutile TiO2 under conditions conducive to flash sintering, it induces the formation of parallel planes of oxygen vacancies. Specif

The nature of dynamic local order in CH$_3$NH$_3$PbI$_3$ and CH$_3$NH$_3$PbBr$_3$

Autor: Weadock, Nicholas, Sterling, Tyler, Vigil, Julian, Gold-Parker, Aryeh, Smith, Ian, Ahammed, Ballal, Krogstad, Matthew, Ye, Feng, Voneshen, David, Gehring, Peter, Steinrück, Hans-Georg, Ertekin, Elif, Karunadasa, Hemamala, Reznik, Dmitry, Toney, Michael

Hybrid lead halide perovskites (LHPs) are a class of semiconductor with novel properties that are distinctively governed by structural fluctuations. Diffraction experiments sensitive to average, long-range order reveal a cubic structure in the device

Occupational Disorder as the Origin of Flattening of the Acoustic Phonon Branches in the Clathrate Ba$_{8}$Ga$_{16}$Ge$_{30}$

Autor: Roy, Susmita, Sterling, Tyler C., Parshall, Daniel, Toberer, Eric, Christensen, Mogens, Adroja, Devashibhai T., Reznik, Dmitry

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 high electrical conductivity. Ba$_{8}$Ga$_{16}$Ge$_{30}$ (BGG) has a

Report

Effect of the electronic charge gap on LO bond-stretching phonons in undoped La$_2$CuO$_4$ calculated using LDA+U

Autor: Sterling, Tyler C., Reznik, Dmitry

Publikováno v: Phys. Rev. B 104 134311 (2021)

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 significantly softer than observed, presumably because of weak on-site Coulomb rep
