Electrical Transport and Joule Heating of ZrB2 Network in SiC Matrix

Semi-classical transport for predicting joule heating in carbon nanotubes

Article history: Received 8 January 2010 Received in revised form 9 March 2010 Accepted 2 April 2010 Available online 10 April 2010 Communicated by R. Wu A method for predicting the joule heating using Monte Carlo simulation for the electron dynamics is proposed. The joule heating in (10,10) carbon nanotubes is computed. The full energy band is utilized; however the results show that for low te...

Thermochemical and Mechanical Stabilities of the Oxide Scale of ZrB2+SiC and Oxygen Transport Mecha

Refractory diboride with silicon carbide additive has a unique oxide scale microstructure with two condensed oxide phases (solid+liquid), and demonstrates oxidation resistance superior to either monolithic diboride or silicon carbide. We rationalize that this is because the silica-rich liquid phase can retreat outward to remove the high SiO gas volatility region, while still holding onto the zi...

Piezoresistive effect in p-type 3C-SiC at high temperatures characterized using Joule heating

Cubic silicon carbide is a promising material for Micro Electro Mechanical Systems (MEMS) applications in harsh environ-ments and bioapplications thanks to its large band gap, chemical inertness, excellent corrosion tolerance and capability of growth on a Si substrate. This paper reports the piezoresistive effect of p-type single crystalline 3C-SiC characterized at high temperatures, using an i...

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...
