A Computational Method for Studying Vibrational Mode Dynamics
Andrew Rohskopf, Ruiyang Li, Tengfei Luo +1
The traditional picture of heat transfer in solids by atomic vibrations, also known as phonons, involves phonons scattering with each other like gas particles and is commonly refer…
Development of Interatomic Potentials to Model the Interfacial Heat Transport of Ge/GaAs
Spencer Wyant, Andrew Rohskopf, Asegun Henry
Molecular dynamics simulations provide a versatile framework to study interfacial heat transport, but their accuracy remains limited by the accuracy of available interatomic potent…
Enhancement of Ion Diffusion by Targeted Phonon Excitation
Kiarash Gordiz, Sokseiha Muy, Wolfgang G. Zeier +2
Ion diffusion is important in a variety of applications, yet fundamental understanding of the diffusive process in solids is still missing, especially considering the interaction o…
Understanding Phonon Transport Properties Using Classical Molecular Dynamics Simulations
Murali Gopal Muraleedharan, Kiarash Gordiz, Andrew Rohskopf +4
Predictive modeling of the phonon/thermal transport properties of materials is vital to rational design for a diverse spectrum of engineering applications. Classical Molecular Dyna…
Modal analysis of heat transfer across crystalline Si and amorphous SiO2 interface
Kiarash Gordiz, Murali Gopal Muraleedharan, Asegun Henry
We studied the anharmonic modal contributions to heat transfer at the interface of crystalline Si and amorphous SiO2 using the recently proposed interface conductance modal analysi…
Thermal interface conductance between aluminum and aluminum oxide: A rigorous test of atomistic level theories
Murali Gopal Muraleedharan, Kiarash Gordiz, Shenghong Ju +3
We report the first ever accurate theoretical prediction of thermal conductance of any material interface. Thermal interfacial conductance of aluminum (Al)-sapphire (α-Al2O3) inter…
