Characterization of ion/electron beam induced deposition of electrical contacts at the sub-μm scale

D. Brunel, David Troadec, D. Hourlier, D. Deresmes, M. Zdrojek, Thierry Melin

We investigate the fabrication of electrical contacts using ion (IBID) - and electron-beam induced deposition (EBID) of platinum at the sub-µm scale. Halos associated with the metal surface decoration in the 0.05-2 µm range are characterized electrically using transport measurements, conducting…

Milliwatt-level output power in the sub-terahertz range generated by photomixing in a GaAs photoconductor

Emilien Peytavit, Sylvie Lepilliet, Francis Hindle, Christophe Coinon, Tahsin Akalin, Guillaume Ducournau, Gaël Mouret, Jean-Francois Lampin

It is shown from accurate on-wafer measurement that continuous wave output powers of 1.2 mW at 50 GHz and 0.35 mW at 305 GHz can be generated by photomixing in a low temperature grown GaAs photoconductor using a metallic mirror Fabry-Pérot cavity. The output power is improved by a factor of about…

Time reversed acoustics techniques for elastic imaging in reverberant and nonreverberant media : an experimental study of the chaotic cavity transducer concept

B. van Damme, K. van den Abeele, Y.F. Li, Olivier Bou Matar

In view of emerging imaging technologies based on the combination of Time Reversed Acoustics (TRA) with Nonlinear Elastic Wave Spectroscopy (NEWS) for the detection and localization of micro-damage in solids, we have investigated the benefits of chirped source signal excitation, inverse filtering…

Magnetic field modulated dielectric relaxation behavior of Pt/BiScO3-PbTiO3/La0.7Sr0.3MnO3 heterostructure in metal-insulator transition region : an equivalent-circuit method

J.Y. Zhu, J. Yang, W. Bai, C.G. Duan, S. Zhang, G.S. Wang, X.L. Dong, Denis Remiens, X.D. Tang

Utilizing temperature and magnetic field dependent dielectric spectroscopy, two different dielectric relaxation processes, both accompanied with prominent positive magnetodielectric (MD) effects, were observed in Pt/BiScO3-PbTiO3/La0.7Sr0.3MnO3 (Pt/BSPT/LSMO) heterostructure. An equivalent circuit…

Frictional contact of two spheres for arbitrary 2D loading

Vladislav Aleshin, Koen van den Abeele

Frictional interaction of two elastic spheres is a fundamental problem of contact mechanics. The tangential displacement depends on the normal and tangential force in a complicated and, in general, hysteretic way. We analyze in detail the key memory characteristic of the system (the traction…

Fluctuation theorem and microreversibility in a quantum coherent conductor

S. Nakamura, Y. Yamauchi, M. Hashisaka, K. Chida, K. Kobayashi, T. Ono, R. Leturcq, K. Ensslin, K. Saito, Y. Utsumi, A.C. Gossard

Mesoscopic systems provide us a unique experimental stage to address nonequilibrium quantum statistical physics. By using a simple tunneling model, we describe the electron exchange process via a quantum coherent conductor between two reservoirs, which yields the fluctuation theorem (FT) in…
