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...

In situ epitaxial surface passivation of GaAlN/GaN HEMT heterostructures grown by LP-MOCVD

Marie-Antoinette Di Forte-Poisson, Nicolas Sarazin, M. Magis, Maurice Tordjman, Erwan Morvan, Raphaël Aubry, J. Di Persio, Bertrand Grimbert

This paper reports on in situ passivation studies of GaAlN/GaN High electron mobility transistors (HEMT) structures grown by low-pressure metalorganic vapour phase epitaxy (LP-MOVPE) on sapphire and silicon carbide substrates. GaN, GaAlN, AlN and AlN/GaN superlattice (SL) layers have been deposited...

Selective filtering of confined optical waves in a straight waveguide coupled to a lateral stub

Yan Pennec, Maxime Beaugeois, Bahram Djafari-Rouhani, Abdellatif Akjouj, Jerome O. Vasseur, L. Dobrzynski, Jean-Pierre Vilcot, Mohamed Bouazaoui, J.P. Vigneron

We report numerical simulations, based on a finite difference time domain (FDTD) method, of light propagation in two-dimensional semiconductor micro optical waveguides coupled to one or several lateral stubs. The incident wave which is of transverse magnetic polarization (TM) is either...
