Size-dependence of the exciton transitions in colloidal CdTe quantum dots

Esther Groeneveld, Christophe Delerue, Guy Allan, Yann-Michel Niquet, Celso de Mello Donega

In this paper, we present a detailed investigation of the size dependence of the optical transitions of colloidal CdTe QDs ranging in diameter from 2.9 to 14.8 nm. The energy integrated absorption cross section per CdTe unit is investigated in detail for the lowest two exciton transitions (1S3/2(h...

Low-frequency noise in Schottky-barrier-based nanoscale field-effect transistors

N. Clement, G. Larrieu, Emmanuel Dubois

Investigation of low-frequency noise in nanoscale Schottky-barrier (SB)-based field-effect transistors (SB-FETs) is of prime importance due to its large amplitude in emerging bottom-up devices. In addition, noise can give additional information on charge transport mechanisms. In this paper, we...

Experimental evidence of zero-angle refraction and acoustic wave-phase control in a two-dimensional solid/solid phononic crystal

Jerome O. Vasseur, B. Morvan, A. Tinel, N. Swinteck, Anne-Christine Hladky, P.A. Deymier

The square symmetry of the equifrequency contour of longitudinal waves in a solid/solid two-dimensional phononic crystal (PC) is shown through numerical calculations and experiments to lead to peculiar propagation phenomena. A slab of steel/epoxy PC immersed in water refracts incident longitudinal...

Investigation of optical and chemical bond properties of hydrogenated amorphous silicon nitride for optoelectronics applications

Etienne Herth, H Desré, Emmanuelle Algré, Christiane I. Legrand, Tuami Lasri

The aim of this work is to determine optimal deposition parameters of silicon nitride for optical applications. The authors present the investigation of hydrogenated amorphous silicon nitride SiNx:H deposited by the low temperature PECVD method in high frequency reactors. The study of hydrogen...

Supercurrent and multiple Andreev reflections in an InSb nanowire Josephson junction

Henrik Nilsson, Peter Samuelsson, Philippe Caroff, Hongqi Xu

Epitaxially grown, high quality semiconductor InSb nanowires are emerging material systems for the development of high performance nanoelectronics and quantum information processing and communication devices, and for the studies of new physical phenomena in solid state systems. Here, we report on...

Nanometer-scale, quantitative composition mappings of InGaN layers from a combination of scanning transmission electron microscopy and energy dispersive x-ray spectroscopy

K. Pantzas, G. Patriarche, David Troadec, S. Gautier, T. Moudakir, S. Suresh, L. Largeau, O. Mauguin, P. L. Voss, A. Ougazzaden

Using elastic scattering theory we show that a small set of energy dispersive x-ray spectroscopy (EDX) measurements is sufficient to experimentally evaluate the scattering function of electrons in high-angle annular dark field scanning transmission microscopy (HAADF-STEM). We then demonstrate how...

60 GHz membrane antennas fed by substrate integrated waveguide

Tristan Sarrazin, Hamsakutty Vettikalladi, Olivier Lafond, Mohamed Himdi, N. Rolland

MODERN multimedia applications demand higher data rates. This has been recently proven by the accelerating sales of IEEE 802.11 family WLAN hardware. Current WLANs are, however, capable of delivering only 30-100 Mb/s connection speeds, which is insufficient for future applications like wireless...
