New developments on diamond photodetector for VUV solar observations

Ali Benmoussa, Ali Soltani, Ken Haenen, Udo Kroth, Vincent Mortet, Hassan Ali Barkad, David Bolsée, Christian Hermans, M. Richter, Jean-Claude de Jaeger, Jean-François Hochedez

A new large-size metal–semiconductor–metal photoconductor device of 4.6 mm in diameter based on diamond material has been reprocessed and characterized in the vacuum-ultraviolet (VUV) wavelength range. The metal finger contacts have been processed to 2 µm in width with spacing between the contacts…

1.55 µm GaAs/GaNAsSb/GaAs optical waveguides grown by radio frequency nitrogen plasma-assisted molecular beam epitaxy

Kianhuan Tan, Soon Fatt Yoon, Wan Khai Loke, Satrio Wicaksono, Zhichuan Xu, Tien Khee Ng, Kim Luong Lew, N. Saadsaoud, Malek Zegaoui, Didier Decoster, Jean Chazelas

We demonstrate a 1.55 μm GaAsGaNAsSbGaAs optical waveguide grown by molecular beam epitaxy as an alternative to the AlGaAsGaAs system. The 0.4-μm -thick GaNAsSb guiding layer contains ∼3.5% of N and 9% of Sb, resulting in optical band gap of 0.88 eV. The refractive index of the GaNAsSb layer was…

Unified and stable scattering matrix formalism for acoustic waves in piezoelectric stacks

Victor Y. Zhang, Vincent Laude

This paper presents a unified and full scattering matrix (s-matrix) formalism for modeling of acoustic waves in piezoelectric multilayered structures. A stable recursive algorithm is derived for computation of the total s-matrix of a stack in terms of the interface s-matrix, both referring to the…

Electrochemical impedance spectroscopy and surface plasmon resonance studies of DNA hybridization on gold/SiO_<i>x</i> interfaces

Maël Manesse, Valérie Stambouli, Rabah Boukherroub, Sabine Szunerits

The use of Au/SiO_<i>x</i> interfaces for the investigation of DNA hybridization using electrochemical impedance spectroscopy (EIS) and surface plasmon resonance (SPR) simultaneously is demonstrated. Standard glass chemistry was used to link single-stranded DNA (ss…

Time-resolved detection of single-electron interference

S. Gustavsson, R. Leturcq, M. Studer, T. Ihn, K. Ensslin, D.C. Driscoll, A.C. Gossard

We demonstrate real-time detection of self-interfering electrons in a double quantum dot embedded in an Aharonov-Bohm interferometer, with visibility approaching unity. We use a quantum point contact as a charge detector to perform time-resolved measurements of single-electron tunneling. With…
