Metavalent bonding in crystalline solids: how does it collapse?
L. Guarneri, S. Jakobs, A. von Hoegen +10
The chemical bond is one of the most powerful, yet controversial concepts in chemistry, explaining property trends in solids. Recently, a novel type of chemical bonding has been id…
Short range order and topology of GeGaTe glasses
Ildikó Pethes, Andrea Piarristeguy, Annie Pradel +4
Chemical short range order and topology of GeGaTe glasses was investigated by neutron- and x-ray diffraction as well as Ge and Ga K-edge extended x-ray absor…
Local order in binary Ge-Te glasses - an experimental study
Pál Jóvári, Andrea Piarristeguy, Annie Pradel +5
The structure of (x = 14.5, 18.7, 23.6) glasses prepared by twin roller quenching technique was investigated by neutron diffraction, X-ray diffra…
Structure of chalcogenide glasses by neutron diffraction
Gabriel Cuello, Andrea Piarristeguy, Alejandro Fernandez-Martinez +2
The purpose of this work is to study the change in the structure of the Ge-Se network upon doping with Ag. The total structure factor S(Q) for two samples has been measured by neut…
Technology challenges for space interferometry: the option of mid-infrared integrated optics
L. Labadie, P. Kern, P. Labeye +5
Nulling interferometry is a technique providing high angular resolution which is the core of the space missions Darwin and the Terrestrail Planet Finder. The first objective is to…
Transmission measurement at 10.6 microns of Te2As3Se5 rib-waveguides on As2S3 substrate
C. Vigreux-Bercovici, E. Bonhomme, A. Pradel +3
The feasibility of chalcogenide rib waveguides working at lambda = 10.6 microns has been demonstrated. The waveguides comprised a several microns thick Te2As3Se5 film deposited by…
