... by the linearization method used in this work. Integration of this method into an iterative scheme for temperature and frequency dependent phonon transport would potentially offer even greater speedups combined with acceleration methods presented in this research. Potential further speedups could come from using...

...Xin Ran; Moran Wang A steady-state Monte Carlo scheme is developed for phonon transport based on the energy-based deviational phonon Boltzmann transport equation (PBTE). Other than tracking trajectories and time evolution of each packet in the transient methods, this steady-state method determines...

.... BTE phonon transport microscale heat conduction finite volume solution acceleration Over the last two decades, thermal management has emerged as a critical bottleneck to the continued scaling of microelectronics [ 1 , 2 ]. The move to finFETs and thin-body multigate devices has led...

... Silicon-on-insulator (SOI) technology has sparked advances in semiconductor and MEMs manufacturing and revolutionized our ability to study phonon transport phenomena by providing single-crystal silicon layers with thickness down to a few tens of nanometers. These nearly perfect crystalline silicon layers...

... films thermal conductivity supported graphene phonon transport measurement Graphene is a monatomic sheet of sp 2 bonded carbon atoms. After graphene was first mechanically exfoliated from graphite onto a dielectric substrate in 2004 ( 1 ), it has received intense interest...

...Lin Sun; Jayathi Y. Murthy Detailed phonon transport at Si/Ge interfaces is studied using the molecular dynamics wave-packet method. Three types of interfaces are investigated: A smooth interface, an interface with random roughness, and an interface with a regularly patterned roughness. The phonon...
