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…

Intrinsic current gain cutoff frequency of 30 GHz with carbon nanotube transistors

A. Le Louarn, F. Kapche, Jean-Marc Bethoux, Henri Happy, Gilles Dambrine, Vincent Derycke, Pascale Chenevier, N. Izard, M. F. Goffman, Jean-Philippe Bourgoin

High frequency capabilities of carbon nanotube field-effect transistors (CNTFETs) are investigated. Structures with a large number of single-walled carbon nanotubes were fabricated using dielecrophoresis to increase the density of nanotubes in the device channel. The authors obtained an intrinsic…
