Electronic and thermal properties of the phase-change memory material, Ge2Sb2Te5, and results from spatially resolved transport calculations
Kishor Nepal, Aashish Gautam, Ridwan Hussein +4
We report new insights into the electronic, structural, and transport (heat and charge) properties of the phase-change memory material Ge2Sb2Te5. Using realistic structural models…
Electronic conduction in copper-graphene composites with functional impurities
Kishor Nepal, Ridwan Hussein, Yahya Al-Majali +1
Coal-derived graphene-like material and its addition to FCC copper are investigated using ab initio plane wave density functional theory (DFT). We explore ring disorder in the sp2…
Spatially Local Estimates of the Thermal Conductivity of Materials
C. Ugwumadu, A. Gautam, Y. G. Lee +1
In this paper we describe a spatial decomposition of the thermal conductivity, what we name "site-projected thermal conductivity", a gauge of the thermal conduction activity at eac…
Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten
C. Ugwumadu, D. A. Drabold, R. Tutchton
The impact of irradiation on the thermal and electronic properties of materials is a persistent puzzle, particularly defect formation at the atomic and nanoscales. This work examin…
