We show that the observed nonmonotonic behavior of the thermal conductance between two nanoparticles when they are brought into contact is originated by an intricate phase space dynamics. Here it is assumed that this dynamics results from the thermally activated jumping through a rough energy landscape. A hierarchy of relaxation times plays the key role in the description of this complex phase ...

A normal full-contact graphene/substrate interface has been reported to have a thermal conductance in the order of 10(8) Wm(-2)K(-1). The reported work used a sandwiched structure to probe the interface energy coupling, and the phonon behavior in graphene was significantly altered in an undesirable way. Here, we report an intriguing study of energy coupling across unconstrained graphene/substra...

in this paper, we study the plasmonic thermal conductance of ordered stacks of metallic nanorings in a host material. using second quantized formalism of the random phase approximation, we first determine the dispersion relations of surface plasmon waves on the stacks of nanorings. then, using landauer-buttiker formalism, we determine the coefficient of plasmonic thermal conductance and heat cu...

A program of model development and experimentation has been undertaken to develop innovative methods to provide predictable and controllable thermal barrier regions for solid breeder blankets. In particular, particle beds have been studied because of their unique thermalhydraulic properties. It has been demonstrated that large variations in thermal conductance can be obtained in the thermal bar...

Novel two-dimensional (2D) materials show unusual physical properties which combined with strain engineering open up the possibility of new potential device applications in nanoelectronics. In particular, transport properties have been found to be very sensitive to applied strain. In the present work, using a density-functional based tight-binding (DFTB) method in combination with Green's funct...
