Ultrafast Heat Transfer at the Nanoscale: Controlling Heat Anisotropy

open access: yesACS Photonics, 2023
International audience ; Thermoplasmonics has benefited from increasing attention in recent years by exploiting the photothermal effects within plasmonic nanoparticles to generate nanoscale heat sources. Recently, it has been demonstrated that exciting gold nanoparticles with ultrashort light pulses could be used to achieve high-speed light management ...

Investigation of Heat Diffusion at Nanoscale Based on Thermal Analysis of Real Test Structure

open access: yesEnergies, 2020
This paper presents an analysis related to thermal simulation of the test structure dedicated to heat-diffusion investigation at the nanoscale. The test structure consists of thin platinum resistors mounted on wafer made of silicon dioxide. A bottom part

Control of near-field radiative heat transfer based on anisotropic 2D materials

open access: yesAIP Advances, 2018
In this work, we study the near-field radiative heat transfer between two suspended sheets of anisotropic 2D materials. It is found that the radiative heat transfer can be enhanced with orders-of-magnitude over the blackbody limit for nanoscale ...

Photothermal heating and heat transfer analysis of anodic aluminum oxide with high optical absorptance

open access: yesNanophotonics, 2022
Photothermal heating with metallic nanostructures has the unique property of generating heat at the nanoscale owing to plasmon resonances. In this study, the heat transfer of anodic aluminum oxides (AAOs) coated with plasmonic titanium nitride (TiN) of ...

Heat Diode Effect and Negative Differential Thermal Conductance across Nanoscale Metal-Dielectric Interfaces

open access: yes, 2013
Controlling heat flow by phononic nanodevices has received significant attention recently because of its fundamental and practical implications. Elementary phononic devices such as thermal rectifiers, transistors, and logic gates are essentially based on

Thermal conductivity in harmonic lattices with random collisions [PDF]

open access: yes, 2015
We review recent rigorous mathematical results about the macroscopic behaviour of harmonic chains with the dynamics perturbed by a random exchange of velocities between nearest neighbor particles.

Radiative heat transfer between nanoparticles enhanced by intermediate particle

open access: yesAIP Advances, 2016
Radiative heat transfer between two polar nanostructures at different temperatures can be enhanced by resonant tunneling of surface polaritons. Here we show that the heat transfer between two nanoparticles is strongly varied by the interactions with a ...

Quantum heat transfer: A Born Oppenheimer method

open access: yes, 2010
We develop a Born-Oppenheimer type formalism for the description of quantum thermal transport along hybrid nanoscale objects. Our formalism is suitable for treating heat transfer in the off-resonant regime, where e.g., the relevant vibrational modes of ...

Magneto-thermoplasmonics: from theory to applications

open access: yes, 2018
We review recent theoretical developments on the nanoscale radiative heat transfer in magneto-optical many-particle systems. We discuss in detail the circular heat flux, the giant magneto-resistance effect, the persistent heat current, and the thermal ...

Dimension- and shape-dependent thermal transport in nano-patterned thin films investigated by scanning thermal microscopy [PDF]

open access: yes, 2017
Scanning thermal microscopy (SThM) is a technique which is often used for the measurement of the thermal conductivity of materials at the nanometre scale. The impact of nano-scale feature size and shape on apparent thermal conductivity, as measured using
