Structural and Mechanical Properties of Double Wall Carbon Nanotubes

Bacsa R.R., Bacsa W.S., Flahaut E., Laurent Ch., Peigney A., Puech P., LPST Université Paul Sabatier, FR

Narrow diameter double walled carbon nanotubes can now be grown by the catalytic chemical vapor deposition process with high yield. Double walled carbon nanotubes are the molecular analogs to coaxial cables and they can also [...]

Local Optical Field in the Neighborhood of Structured Surfaces: Phase Singularities and Talbot Effect

Amien C., Bacsa W.S., Caumont M., Chaudret B., Dwir B., Levine B., LPST Université Paul Sabatier, FR

We have probed the local optical field in the vicinity of structured surfaces to observe optical coherence effects. We have used a sub -wavelength sized optical fiber probe to map the local field of microgratings [...]
