Study of the influence of the molecular organization on single-layer OLEDs' performances
Laurent Aubouy, Philippe Gerbier, Christian Guérin +3
The authors synthesized three new silole derivs. with incrementally flexible structure to tune their packing ability and therefore study the influence of the mol. organization in s…
Evidence of environmental strains on charge injection in silole based organic light emitting diodes
Nolwenn Huby, Lionel Hirsch, Laurent Aubouy +4
Using d. functional theory (DFT) computations, the authors demonstrated a substantial skeletal relaxation when the structure of 2,5-bis-[4-anthracene-9-yl-phenyl]-1,1-dimethyl-3,4-…
Use of resonance Raman spectroscopy to study the phase diagram of PbZr0.52Ti0.48O3
Jerome Rouquette, Julien Haines, Véronique Bornand +3
Evidence is presented for the first time that the sharp and continuous spectral changes observed in PbZr0.52Ti0.48O3 (PZT) between 350 and 10 K with the 647.1 nm wavelength are due…
GaAs:Mn nanowires grown by molecular beam epitaxy of (Ga,Mn)As at MnAs segregation conditions
J. Sadowski, P. Dluzewski, S. Kret +7
GaAs:Mn nanowires were obtained on GaAs(001) and GaAs(111)B substrates by molecular beam epitaxial growth of (Ga,Mn)As at conditions leading to MnAs phase separation. Their density…
Imaging the stick-slip peeling of an adhesive tape under a constant load
Pierre-Philippe Cortet, Matteo Ciccotti, Loic Vanel
Using a high speed camera, we study the peeling dynamics of an adhesive tape under a constant load with a special focus on the so-called stick-slip regime of the peeling. It is the…
Dynamic condensation of water at crack tips in fused silica glass
M. Ciccotti, M. George, V. Ranieri +2
Water molecules play a fundamental role in the physics of slow crack propagation in glasses. It is commonly understood that, during stress-corrosion, water molecules that move in t…
