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…

Power performance at 40 GHz on quaternary barrier InAlGaN/GaN HEMT

François Lecourt, Alain Agboton, Nico Ketteniss, Hannes Behmenburg, N. Defrance, Virginie Hoel, Holger Kalisch, Andrei Vescan, Michael Heuken, Jean-Claude de Jaeger

Depletion-mode high-electron mobility transistors (HEMTs) based on a quaternary barrier In 0.11 Al 0.72 Ga 0.17 N/GaN heterostructure on sapphire substrate are fabricated and characterized. This structure shows a very high Hall electron mobility of 2200 cm 2 /V·s, which is the highest value ever…

Multiple exciton generation and ultrafast exciton dynamics in HgTe colloidal quantum dots

Ali Al-Otaify, Stephen V. Kershaw, Shuchi Gupta, Andrey L. Rogach, Guy Allan, Christophe Delerue, David J. Binks

The investigation of sub-nanosecond exciton dynamics in HgTe colloidal quantum dots using ultrafast transient absorption spectroscopy is reported. The transmittance change spectrum acquired immediately after pumping is dominated by a bleach blue-shifted by ∼200–300 nm from the photoluminescent…

Improvement of the oxidation interface in an AlGaAs/AlxOy waveguide structure by using a GaAs/AlAs superlattice

J.Y. Song, S. Bouchoule, G. Patriarche, E. Galopin, A.M. Yacomotti, E. Cambril, Q.G. Kou, David Troadec, J.J. He, J.C. Harmand

The wet oxidation from the mesa sidewalls of AlGaAs/GaAs epitaxial structures is investigated in details. In addition to the intended lateral oxidation of the Al-rich buried layer, we observe a parasitic vertical oxidation of the adjacent layers of lower Al content. This vertical oxidation produces…

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…
