Modeling Heterogeneous Melting in Phase Change Memory Devices
Jake Scoggin, Zachary Woods, Helena Silva +1
We present thermodynamic crystallization and melting models and calculate phase change velocities in based on kinetic and thermodynamic parameters. The calculated…
Negative thermal expansion near the precipice of structural stability in open perovskites
Connor A. Occhialini, G. G. Guzmán-Verri, Sahan U. Handunkanda +1
Negative thermal expansion (NTE) describes the anomalous propensity of materials to shrink when heated. Since its discovery, the NTE effect has been found in a wide variety of mate…
Chemical-Strain Induced Tilted Dirac Nodes in (BEDT-TTF)X (X = I, Cl, Br, F) Based Charge-Transfer Salts
R. Matthias Geilhufe, Benjamin Commeau, Gayanath W. Fernando
The identification of novel multifunctional Dirac materials has been an ongoing effort. In this connection quasi 2-dimensional (BEDT-TTF)-based charge transfer salts are widely dis…
Polarization rotation in BiTiO by isovalent doping at the fluorite sublattice
Kevin Co, Fu-Chang Sun S. Pamir Alpay, Sanjeev K. Nayak
Bismuth titanate, BiTiO (BiT), is a complex layered ferroelectric material that is composed of three perovskite-like units and one fluorite-like unit stacked alterna…
Materials Informatics for Dark Matter Detection
R. Matthias Geilhufe, Bart Olsthoorn, Alfredo Ferella +4
Dark Matter particles are commonly assumed to be weakly interacting massive particles (WIMPs) with a mass in the GeV to TeV range. However, recent interest has shifted towards ligh…
Activation Energy of Metastable Amorphous Ge2Sb2Te5 from Room Temperature to Melt
S. Muneer, J. Scoggin, F. Dirisaglik +7
Resistivity of metastable amorphous Ge2Sb2Te5 (GST) measured at device level show an exponential decline with temperature matching with the steady-state thin-film resistivity measu…
