Reticulating Local Dynamics in Three-Dimensional Covalent Organic Frameworks
Francesco Tavani, Saber Mirzaei, M. Saeed Mirzaei +7
In covalent organic frameworks (COFs), the geometry of the building units predetermines the structure of the framework, yet comparable design principles relating the COF linkers to…
Surface Magnetism in FeGeTe Crystals
T. A. Tyson, S. Amarasinghe, AM M. Abeykoon +6
The surface magnetization of FeGeTe was examined by low-energy electron microscopy (LEEM) using an off-normal incidence electron beam. We found that the 180 domain wall…
High magnetic anisotropy and magnetocaloric effects in single crystal CrTe
Anirban Goswami, Nicholas Ng, AM Milinda Abeykoon +2
We report a systematic investigation of anisotropic magnetocaloric effects in single crystal CrTe. Single crystal samples are synthesized by chemical vapor transport and ch…
Nanoscale Sn off-centering behind low thermal conductivity in SnSe thermoelectric
E. S. Bozin, H. Xie, A. M. M. Abeykoon +4
The local atomic structure of SnSe was characterized across its orthorhmbic-to-orthorhombic structural phase transition using x-ray pair distribution function analysis. Substantial…
Suppression of Superconductivity and Nematic Order in FeSeS (01, 0.1) Crystals by Anion Height Disorder
Aifeng Wang, Ana Milosavljevic, A. M. Milinda Abeykoon +10
Connections between crystal chemistry and critical temperature have been in the focus of superconductivity, one of the most widely studied phenomena in physics, chemistry and…
Kondo-induced giant isotropic negative thermal expansion
D. G. Mazzone, M. Dzero, M. Abeykoon +9
Negative thermal expansion is an unusual phenomenon appearing in only a handful of materials, but pursuit and mastery of the phenomenon holds great promise for applications across…
Absence of Local Fluctuating Dimers in Superconducting Ir(Pt,Rh)Te
R. Yu, S. Banerjee, H. Lei +6
The compound IrTe2 is known to exhibit a transition to a modulated state featuring Ir-Ir dimers, with large associated atomic displacements. Partial substitution of Pt or Rh for Ir…
Enhanced Thermoelectric Power and Electronic Correlations in RuSe
Kefeng Wang, Aifeng Wang, A. Tomic +5
We report the electronic structure, electric and thermal transport properties of RuIrSe (). RuSe is a semiconductor that crystallizes in a cubic p…
Nature of Structural Changes Near the Magnetic Ordering Temperature in Small-Ion Rare Earth Perovskites RMnO3
T. Yu, T. A. Tyson, H. Y. Chen +3
Detailed structural measurements were conducted on a new perovskite, ScMnO3, and on orthorhombic LuMnO3. Complementary density functional theory (DFT) calculations were carried out…
Local Structural Evidence for Strong Electronic Correlations in LiRhO Spinel
K. R. Knox, A. M. M. Abeykoon, H. Zheng +5
The local structure of the spinel LiRhO has been studied using atomic pair distribution function (PDF) analysis of powder x-ray diffraction data. This measurement is sensit…
