Journal ArticleDOI
Mechanical properties of carbon nanotubes
Jean-Paul Salvetat,Jean-Marc Bonard,Neil H. Thomson,Andrzej J. Kulik,László Forró,W. Benoit,Libero Zuppiroli +6 more
TL;DR: A variety of outstanding experimental results on the elucidation of the elastic properties of carbon nanotubes are fast appearing as discussed by the authors, which are based mainly on the techniques of high-resolution transmission electron microscopy and atomic force microscopy (AFM) to determine the Young's moduli of single-wall nanotube bundles and multi-walled nanotubels.
Journal ArticleDOI
Highly phosphorescence iridium complexes and their application in organic light-emitting devices.
Md. K. Nazeeruddin,Robin Humphry-Baker,D. Berner,Simon Rivier,Libero Zuppiroli,Michael Graetzel +5 more
TL;DR: A new series of iridium(III) mixed ligand complexes developed and fully characterized by UV-vis, emission, IR, NMR, and cyclic voltammetric studies show emission maxima in the blue, green, and yellow region of the visible spectrum and exhibit unprecedented phosphorescence quantum yields.
Journal ArticleDOI
High mobility n‐type charge carriers in large single crystals of anatase (TiO2)
TL;DR: In this article, resistivity, thermopower, and Hall-effect measurements on large single crystals of the anatase form of TiO2 all indicate high mobility n-type carriers that are produced by thermal excitation from a density of ∼1018 cm−3 putatively present shallow donor states.
Journal ArticleDOI
Water Vapor and Oxygen Degradation Mechanisms in Organic Light Emitting Diodes
TL;DR: The degradation of organic light emitting diodes (OLEDs) due to the growth of dark spots can be attributed to the synergy of three external causes: dust particles deposited during the fabrication process, pollution by water vapor, and pollution by oxygen as mentioned in this paper.
Journal ArticleDOI
Hopping in disordered conducting polymers
TL;DR: This paper addresses some important questions concerning hopping conduction in doped conducting polymers, i.e., dimensionality, homogeneity, adiabaticity, Coulomb interactions, and multiphonon character.
