Reduction of stacking faults in (11$ \bar 2 $0) and (11$ \bar 2 $2) GaN films by ELO techniques and benefit on GaN wells emission

Z. Bougrioua, M. Laügt, P. Vennegues, I. Cestier, T. Gühne, E. Frayssinet, P. Gibart, M. Leroux

New conditions for one‐step ELO were implemented to grow coalesced (11equation image0) non‐polar and (11equation image2) semi‐polar GaN layers starting, respectively, from R ‐ and M ‐plane sapphire. A great part of the stacking faults (SFs) and dislocations are filtrated resulting in GaN material…

Templates for LaAlO3 epitaxy on silicon

Pierre Boulenc, Isabelle Devos

As direct epitaxy of crystalline LaAlO3 on silicon has not been realized yet, we investigated the use of a template between the high-κ and the substrate. We performed calculations in the Density Functional Theory framework for two possible templates: a Sr0.5O monolayer and a 0.5 nm thick γ-Al2O3(0…

CVD growth of carbon nanotubes at very low pressure of acetylene

Yu.A. Kasumov, A. Shailos, I.I. Khodos, V.T. Volkov, V.I. Levashov, V.N. Matveev, Sophie Guéron, Mathias Kobylko, Mathieu Kociak, Helene Bouchiat, Vincent Agache, Anne-Sophie Rollier, Lionel Buchaillot, Anne Marie Bonnot, A.Yu. Kasumov

We present a new technique for CVD synthesis of carbon nanotubes without any gas flow and using a very low pressure of acetylene (down to 0.5 mbar). The good quality of obtained nanotubes is confirmed by TEM observation and electron diffraction patterns, Raman spectroscopy and electron transport…
