Thermal conductivity and thermal boundary resistance of nanostructures

Thermal conductivity and thermal boundary resistance of nanostructures

: We present a fabrication process of low-cost superlattices and simulations related with the heat dissipation on them. The influence of the interfacial roughness on the thermal conductivity of semiconductor/semiconductor superlattices was studied by equilibrium and non-equilibrium molecular dynamics and on the Kapitza resistance of superlattice's interfaces by equilibrium molecular dynamics. T...

Dramatic thermal conductivity reduction by nanostructures

Thermal Contact Resistance and Thermal Conductivity of a Carbon Nanofiber

We have measured the thermal resistance of a 152-nm-diameter carbon nanofiber before and after a platinum layer was deposited on the contacts between the nanofiber and the measurement device. The contact resistance was reduced by the platinum coating for about 9–13% of the total thermal resistance of the nanofiber sample before the platinum coating. At a temperature of 300 K, the axial thermal ...

Thermal Conductivity and Thermal Contact Resistance of Metal Foams

Unique specifications of metal foams such as relatively low cost, ultra-low density, high surface-area-to-volume ratio, and most importantly, the ability to mix the passing fluid provide them a great potential for a variety of thermal-fluidics

Effective Thermal Conductivity of Graded Nanocomposites with Interfacial Thermal Resistance

This work employs the self-consistent method to investigate the effective thermal conductivity distribution in functionally graded materials (FGMs) considering the Kapitza interfacial thermal resistance. A heat conduction solution is first derived for one spherical particle embedded in a graded matrix with a prefect interface. The interfacial thermal resistance of a nanoparticle is simulated by...
