Joule heating in spin Hall geometry

Joule heating in single-walled carbon nanotubes

Joule heating in single-walled carbon nanotubes CNTs using a quantum mechanical approach is presented in this paper. The modeling is based on the energy transfer between the electrons and both acoustic and optical phonons. In this formulation, only the knowledge of the full energy dispersion relation, phonon dispersion relation, and the electron-phonon coupling potential is required for the cal...

Investigation of Self-Heating Phenomenon in Small Geometry Vias Using Scanning Joule Expansion Microscopy

This paper reports the use of a novel thermometry technique, scanning Joule expansion microscopy (SJEM), to study the steady state and dynamic thermal behavior of small geometry vias under sinusoidal and pulsed current stress for the first time. Spatial distribution of temperature rise surrounding a sub-micron via has been determined and the corresponding temperature contour image has been extr...

Joule Heating Effects on Insulator-based Dielectrophoresis

ABSTRACT We present an experimental and numerical study of Joule heating in a polymeric insulator-based dielectrophoresis (iDEP) device. In this study, we used a microscale thermometry technique based upon the temperature-sensitive fluorescence of Rhodamine B dye to monitor the fluid temperature within our iDEP microfluidic devices. We then complemented our experiments with 3D finite element si...
