Slip-dominated structural transitions
Kanka Ghosh, Oguz Umut Salman, Sylvain Queyreau +1
We use molecular dynamics to show that plastic slip is a crucial component of the transformation mechanism of a square-to-triangular structural transition. The latter is a stylized…
Significant four-phonon scattering and its heat transfer implications in crystalline GeSbTe
Kanka Ghosh, Andrzej Kusiak, Jean-Luc Battaglia
We systematically demonstrate the temperature-dependent thermal transport properties in crystalline GeSbTevia first-principles density functional theory-informed linear…
Phonon hydrodynamics in crystalline materials
Kanka Ghosh, Andrzej Kusiak, Jean-Luc Battaglia
Phonon hydrodynamics is an exotic phonon transport phenomenon that challenges the conventional understanding of diffusive phonon scattering in crystalline solids. It features a pec…
Effect of characteristic size on the collective phonon transport in crystalline GeTe
Kanka Ghosh, Andrzej Kusiak, Jean-Luc Battaglia
We study the effect of characteristic size variation on the phonon thermal transport in crystalline GeTe for a wide range of temperatures using the first-principles density-functio…
Phonon hydrodynamics in crystalline GeTe at low temperature
Kanka Ghosh, Andrzej Kusiak, Jean-Luc Battaglia
A first-principles density functional method along with the direct solution of linearized Boltzmann transport equations are employed to systematically analyze the low-temperature t…
Thermal conductivity of amorphous and crystalline GeTe thin film at high temperature: Experimental and theoretical study
Kanka Ghosh, Andrzej Kusiak, Pierre Noé +2
Thermal transport properties bear a pivotal role in influencing the performance of phase change memory (PCM) devices, in which the PCM operation involves fast and reversible phase…
