The potential, time, and concn. dependence of the potentiostatic electropolymn. of the thienyl-substituted transition metal complex [Os(bttpy)22+] onto platinum disk microelectrodes is reported, bttpy is 4'-(5-(2,2'-bithienyl))-2,2':6',2''-terpyridine. Oxi ...
The aim of this thesis work is to study the spin-dependent transport in multiwalled carbon nanotubes (MWNT). To do so, the electrical resistance of MWNT contacted between ferromagnetic electrodes has been measured, as a function of the contacts magnetic co ...
Localized electrochemical deposition (LECD) is an emerging technology for inexpensive and effective fabrication of high-aspect-ratio microstructure of diverse materials. Microradiology with coherent X-rays enabled study of this process in real-time. This l ...
We report on a study of pentacene thin-films grown by high vacuum deposition on silicon dioxide, using atomic force microscopy (AFM) and transmission electron microscopy (TEM). The nucleation density of pentacene islands on SiO2is found to rise ...
Understanding the growth mechanism in molecular organic thin films is fundamental to their applications in organic electronics. We present an extensive study of the growth mechanism of pentacene thin films on silicon dioxide (SiO2) using atomic ...
A flexible method for simultaneous nanoscale structures fabrication and patterning is described, using a combination of stencil mask and pulsed-laser deposition (PLD) techniques. A miniature shadow-mask with nano-apertures in a very thin microfabricated me ...
Deposition of a hydrothermal method has a number of advantages; low deposition temperature, high-purity, deposition on a three-dimensional structure, and a large thickness. The present paper investigates the improvement of an epitaxial lead zirconate titan ...
Experiments using a lens-shaped circular electrode are described to measure the correction of plasma nonuniformity due to the standing wave effect in a large area very high frequency plasma reactor. This work is the experimental verification of the theoret ...
The spin-dependent transport in multiwall carbon nanotubes, obtained by chemical vapour deposition in porous alumina membranes, has been investigated. The zero-bias anomaly is shown to follow the typical power law GT(-alpha) (eV/kT). In the nanotubes conta ...
Firsts results on particle detection using a novel silicon pixel detector are presented. The sensor consists of an array of 48 square pixels with 380 μm pitch based on a n-i-p hydrogenated amorphous silicon (a-Si:H) film deposited on top of a VLSI chip. Th ...
