Minimum and maximum conductance of a thin film layer bridged interface: the role of anharmonicity and layer thickness
Jingjie Zhang, Rouzbeh Rastgarkafshgarkolaei, Carlos A. Polanco +4
We study the role of anharmonicity at interfaces with an added intermediate layer designed to facilitate interfacial phonon transport. Our results demonstrate that while in the har…
Optimizing the interfacial thermal conductance at gold-alkane junctions from 'First Principles'
Jingjie Zhang, Carlos A. Polanco, Avik W. Ghosh
We theoretically explore the influence of end-group chemistry (bond stiffness and mass) on the interfacial thermal conductance at a gold-alkane interface. We accomplish this using…
Design rules for interfacial thermal conductance - building better bridges
Carlos A. Polanco, Rouzbeh Rastgarkafshgarkolaei, Jingjie Zhang +3
We study the thermal conductance across solid-solid interfaces as the composition of an intermediate matching layer is varied. In absence of phonon-phonon interactions, an added la…
Role of crystal structure and junction morphology on interface thermal conductance
Carlos A. Polanco, Rouzbeh Rastgarkafshgarkolaei, Jingjie Zhang +4
We argue that the relative thermal conductance between interfaces with different morphologies is controlled by crystal structure through , the ratio between the {\…
Enhancing phonon flow through 1D interfaces by Impedance Matching
Carlos A. Polanco, Avik W. Ghosh
We extend concepts from microwave engineering to thermal interfaces and explore the principles of impedance matching in 1D. The extension is based on the generalization of acoustic…
Impedance Matching of Atomic Thermal Interfaces Using Primitive Block Decomposition
Carlos A. Polanco, Christopher B. Saltonstall, Pamela M. Norris +2
We explore the physics of thermal impedance matching at the interface between two dissimilar materials by controlling the properties of a single atomic mass or bond. The maximum th…
