Enhanced thermal stability of Pt electrodes for flat epitaxial biferroic-YMnO3/Pt heterostructures
We have investigated the thermal stability of platinum electrodes on oxide substrates for oxide-based devices. We show that flat epitaxial Pt(111) bottom electrodes, deposited on SrTiO3(111) and Al2O3...

The thermal conductivity of pyrolytic char obtained by ultrahigh temperature decomposition of polyethylene specimen via molecular dynamics simulations is investigated as a function of temperature and microstructural characteristics. We find that the simulated thermal conductivity dependence on the average coordination number is modified by formation of graphene-like microtopological features in carbonaceous char. The dependence of thermal conductivity on temperature and average coordination number is explained in terms of an analytical model, based on the Einstein's theory of heat transport. The deviations due to the formation of graphene sheet-like units are taken into consideration by introducing corresponding corrections in the elastic properties of char. ©2009 American Institute of Physics
