Electron delay analysis and image charge effect in AlGaN/GaN HEMT on silicon substrate

Alain Agboton, N. Defrance, Philippe Altuntas, Vanessa Avramovic, Adrien Cutivet, Rezki Ouhachi, Jean-Claude de Jaeger, Samira Bouzid-Driad, Maher, Hassan, M. Renvoise, Peter Frijlink

A delay time analysis is carried out for SiN-passivated AlGaN/GaN High Electron Mobility Transistors (HEMTs) on silicon substrate featuring gate length of 90 nm. The influence of high parasitics in the access pads is considered using de-embedding procedure from the measured S parameters. From the…

Metamaterial-inspired bandpass filter for the terahertz Goubau line

Ali Karami Horestani, Withawat Withayachumnankul, Christophe Fumeaux, Derek Abbott, Tahsin Akalin

Recently, it has been shown that a single wire Goubau line that supports surface wave propagation can be used as an effective terahertz waveguide with low attenuation and low dispersion. In order to fully exploit Goubau lines in terahertz systems, for example for communication applications,…

Structural transitions in ordered supramolecular networks on a semiconductor surface

Guillaume Copie, Christophe Krzeminski, B. Grandidier, Fabrizio Cleri

We report the experimental and theoretical study of the self-assembly of planar organic molecules of the type tris-X-biphenyl-benzene (with X=N, I, Br, CH) on a passivated, boron-doped Si(111)-√3x√3 (R=30°) surface. Ordered molecular structures are observed by high-resolution STM. We perform multi-…

Theoretical and experimental evidence of Fano-like resonances in simple monomode photonic circuits

A. Mouadili, E.H. El Boudouti, A. Soltani, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

A simple photonic device consisting of two dangling side resonators grafted at two sites on a waveguide is designed in order to obtain sharp resonant states inside the transmission gaps without introducing any defects in the structure. This results from an internal resonance of the structure when…
