0.2-μm InP/GaAsSb DHBT power performance with 10 mW/μm² and 25% PAE at 94 GHz

Mohammed Zaknoune, Etienne Okada, Estelle Mairiaux, Yannick Roelens, Damien Ducatteau, Peter Frijlink, Marc Rocchi, Hassan Maher

We report a 94-GHz large-signal load-pull characterization of InP/GaAsSb double heterojunction bipolar transistors. The investigated devices have an emitter area of 0.20 × 9.5 μm2. Biased for highest power added efficiency (PAE), an output power of 6.62 mW/μm2 (11 dBm), a power gain of 5.2 dB, and…

Enhancing LSPR sensitivity of Au gratings through graphene coupling to Au film

Thomas Maurer, Rana Nicolas, Gaëtan Lévêque, P. Subramanian, Julien Proust, Jérémie Béal, Silvere Schuermans, Jean-Pierre Vilcot, Z. Herro, M. Kazan, Jerome Plain, Rabah Boukherroub, Abdellatif Akjouj, Bahram Djafari-Rouhani, Pierre-Michel Adam, Sabine Szunerits

A particular interesting plasmonic system is that of metallic nanostructures interacting with metal films. As the localized surface plasmon resonance (LSPR) behavior of gold nanostructures (Au NPs) on the top of a gold thin film is exquisitely sensitive to the spacer distance of the film-Au NPs, we…

Phosphorus-hyperdoped Si nanocrystals : a model for localized surface plasmon resonance

X. Pi, Christophe Delerue

It has been recently realized that semiconductor nanocrystals can be doped with point defects or impurities up to a very high level, sometimes above the bulk solubility limit. In parallel, hyperdoping has also emerged as a promising means to change the electrical and optical properties of Si. In…

F center in lithium fluoride revisited : comparison of solid-state physics and quantum-chemistry approaches

Ferenc Karsai, Paul Tiwald, Robert Laskowski, Fabien Tran, David Koller, Stefanie Gräfe, Joachim Burgdörfer, Ludger Wirtz, Peter Blaha

We revisit the theoretical description of the F color center in lithium fluoride employing advanced complementary ab initio techniques. We compare the results from periodic supercell calculations involving density-functional theory (DFT) and post-DFT techniques with those from the embedded-cluster…

InAs based Esaki tunnel diodes

Vinay Kumar Chinni, L. Desplanque, Mohamed Zaknoune, Xavier Wallart

We present simulation results of InAs based Esaki tunnel diodes. InAs homojunction and InAs/AlGaSb heterojunction are considered and we investigate the role of source and drain doping levels as well as band energy discontinuities on the tunneling current of the device. The results are very…
