Shift and torsion contact problems for arbitrary axisymmetric normal stress distributions

Grey Sh Boltachev, Vladislav Aleshin

In this paper, we analyze the contact interaction of axisymmetric particles subject to a subsequent application of a constant normal load and a tangential or rotational force. A rigorous solution to the frictional contact problem is given by the known Jäger theorem that presents a relationship…

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…

Raman spectroscopy of self-catalyzed GaAs1-xSbx nanowires grown on silicon

Esther Alarcon Llado, Sònia Conesa-Boj, X. Wallart, Philippe Caroff, Anna Fontcuberta I Morral

Thanks to their wide band structure tunability, GaAs1−xSbx nanowires provide exciting perspectives in optoelectronic and energy harvesting applications. The control of composition and strain of these ternary alloys is crucial in the determination of their optical and electronic properties. Raman…

Experimental demonstration of direct terahertz detection at room-temperature in AlGaN/GaN asymmetric nanochannels

Paul Sangare, Guillaume Ducournau, Bertrand Grimbert, Virginie Brandli, Marc Faucher, Christophe Gaquière, Ana Iniguez-De-La-Torre, Ignacio Íñiguez-De-La-Torre, Jean-Francois Millithaler, Javier Mateos, Tomás González

The potentialities of AlGaN/GaN nanodevices as THz detectors are analyzed. Nanochannels with broken symmetry (so called self switching diodes) have been fabricated for the first time in this material system using both recess-etching and ion implantation technologies. The responsivities of both…

94-GHz load pull measurements of SiGe HBT by extracting output power density in W-band

Issam Hasnaoui, Elodie Canderle, Pascal Chevalier, Daniel Gloria, Christophe Gaquière

In this paper, we present a W-Band load pull test bench used to improve a characterization of Silicon Germanium Heterojunction Bipolar Transistor (SiGe HBT). High accuracy is obtained in Load-pull measurements at 94 GHz on lastgeneration SiGe HBTs by extracting the input reflection hot Sparameter (…
