Low temperature and high pressure Raman and x-ray studies of pyrochlore TbTiO : phonon anomalies and possible phase transition
Surajit Saha, D. V. S Muthu, Surjeet Singh +8
We have carried out temperature and pressure-dependent Raman and x-ray measurements on single crystals of TbTiO. We attribute the observed anomalous temperature depende…
Effect of aging on the reinforcement efficiency of carbon nanotubes in epoxy matrix
Aïssa Allaoui, Pierre Evesque, Jinbo Bai
The reinforcement efficiency of carbon nanotubes (CNTs) in epoxy matrix was investigated in the elastic regime. Cyclic uniaxial tensile tests were performed at constant strain ampl…
Diamond nanoparticles as photoluminescent nanoprobes for biology and near-field optics
A. Cuche, Y. Sonnefraud, O. Faklaris +6
We present results showing the potential of diamond nanoparticles with size less than 50 nm as photoluminescent nanoprobes for serving as stable point-like emitters attached at the…
Nanoscale heat transfer at contact between a hot tip and a substrate
Stéphane Lefèvre, Sebastian Volz, Pierre-Olivier Chapuis
Hot tips are used either for characterizing nanostructures by using scanning thermal microscopes or for local heating to assist data writing. The tip-sample thermal interaction inv…
Heat transfer between a nano-tip and a surface
Pierre-Olivier Chapuis, Jean-Jacques Greffet, Karl Joulain +1
We study quasi-ballistic heat transfer through air between a hot nanometer-scale tip and a sample. The hot tip/surface configuration is widely used to perform nonintrusive confined…
Phenomenological theory of phase transitions in epitaxial BaTiO3 thin films
V. B. Shirokov, Yu. I. Yuzyuk, B. Dkhil +1
We develop a phenomenological thermodynamic theory of ferroelectric BaTiO3 (BT) thin films epitaxially grown on cubic substrates using the Landau-Devonshire eight-order potential.…
