Dopant-vacancy binding effects in Li-doped magnesium hydride
Kyle C. Smith, Timothy S. Fisher, Umesh V. Waghmare +1
We use a combination of ab initio calculations and statistical mechanics to investigate the substitution of Li+ for Mg2+ in magnesium hydride (MgH2) accompanied by the formation of…
Athermal jamming of soft frictionless Platonic solids
Kyle C. Smith, Meheboob Alam, Timothy S. Fisher
A mechanically-based structural optimization method is utilized to explore the phenomena of jamming for assemblies of frictionless Platonic solids. Systems of these regular convex…
Effect of phonon dispersion on thermal conduction across Si/Ge interfaces
Dhruv Singh, Jayathi Y. Murthy, Timothy S. Fisher
We report finite-volume simulations of the phonon Boltzmann transport equation (BTE) for heat conduction across the heterogeneous interfaces in SiGe superlattices. The diffuse mism…
