The relentless shrinking of microelectronic devices makes thermal management an increasingly important topic. To this end, we have developed a computational approach, which allows the prediction of heat flux in nanostructures based on atomistic simulations. As prototypical system, we present results for a silicon — silicon dioxide nanostructure, with (a) abrupt interfaces, and (b) interfaces after...
We determine the thermal conductivity of single layer graphene supported on silicon nitride layer followed by a silicon substrate using a three dimensional simulation study. Temperature distribution profile along the graphene flake is obtained and heat transmission in graphene layer along with the subsequent layers is investigated by modeling the laser light as heat source. Two types of heat sources...
Following an experimental discovery of its extremely high thermal conductivity, graphene was proposed as material for heat removal. To evaluate the feasibility of graphene's use for thermal management we simulated heat propagation in siliconon- insulator (SOI) structures with and without graphene or few-layer graphene (FLG) underlayers. A graphene heat spreader layer, when used, was sandwiched between...
