Generalized interface models for transport phenomena: unusual scale effects in composite nanomaterials
Fabio Pavanello, Fabio Manca, Pier Luca Palla +1
The effective transport properties of heterogeneous nanoscale materials and structures are affected by several geometrical and physical factors. Among them the presence of imperfec…
Impurity impact ionization avalanche in p-type diamond
Vincent Mortet, A. Soltani
Electrical conductivity of a highly boron doped chemical vapor deposited diamond thin film has been studied at different temperatures under high electric field conditions. Current-…
Optical absorption of silicon nanowires
Tao Xu, Yannick Lambert, Christophe Krzeminski +6
We report on simulations and measurements of the optical absorption of silicon nanowires (NWs) versus their diameter. We first address the simulation of the optical absorption base…
Anisotropic Vapor HF etching of silicon dioxide for Si microstructure release
Vikram Passi, Ulf Sodervall, Bengt Nilsson +6
Damages are created in a sacrificial layer of silicon dioxide by ion implantation to enhance the etch rate of silicon-dioxide in liquid and vapor phase hydrofluoric acid. The etch…
Low Frequency Dielectric Loss of Metal/Insulator/Organic Semiconductor Junctions in Ambient Conditions
R. Ledru, S. Pleutin, B. Grouiez +4
The complex admittance of metal/oxide/pentacene thin film junctions is investigated under ambient conditions. At low frequencies, a contribution attributed to proton diffusion thro…
Understanding of the Retarded Oxidation Effects in Silicon Nanostructures
C. Krzeminski, X. -L. Han, G. Larrieu
In-depth understanding of the retarded oxidation phenomenon observed during the oxidation of silicon nanostructures is proposed. The wet thermal oxidation of various silicon nanost…
