Due to their high hardness, high melting point and high chemical stability, transition metal nitrides present a great interest for various applications. This work constitutes a contribution to the understanding of the properties of Nb based binary and tern ...
We have developed hybrid AFM probes with SU-8 polymer body and full platinum and tungsten cantilever and tip. The fabrication process uses surface micromachining of a (100) silicon wafer. The metal (platinum or tungsten) is sputter deposited in oxidation s ...
We report on a dramatic improvement of the optical and structural properties of AlN/GaN multiple quantum wells (MQWs) grown by metal-organic vapor-phase epitaxy using indium as a surfactant. This improvement is observed using photoluminescence as well as x ...
We have developed a new hybrid AFM probe combining an SU-8 polymer body with a full tungsten cantilever having a nanometric tip. The fabrication is based on surface micromachining a silicon wafer, where tungsten is sputter deposited in oxidation sharpened ...
This thesis work focuses on impact and diffusion processes as well as equilibrium positions of a metal deposited on a surface. The metal is deposited in the form of clusters containing n atoms in a controlled way. Gold or silver clusters cations (Au+n and ...
Strontium barium niobate (SrxBa1-xNb2O6, shortly SBN) is a solid solution system with tetragonal tungsten bronze crystal structure. It exhibits a ferroelectric phase with only one polar axis and a transition temperature depending on the Sr/Ba ratio. This t ...
Because of their outstanding mechanical and chemical properties, transition metal nitrides are widely accepted materials in the protective coatings industry. This work aims at elucidating the origin of their exceptional properties. The study concentrates o ...
In the framework of this thesis molecular nanostructures have been engineered on surfaces and are characterized using a variety of techniques. Two types of molecules have been used: carbon nanotubes (CNT) and 4-[trans-2-(pyrid-4-yl-vinyl)] benzoic acid (PV ...
Cluster calculations employing hybrid density functional theory have been carried out to examine the initial surface reactions in atomic layer deposition (ALD) of TiN thin films on the SiO2 surface using TiCl4 and NH3 as precursors. The potential energy su ...
TiN/AlTiN, TiN/CrN and CrN/AlTiN multilayer coatings have been deposited by the cathodic arc evaporation technique. The period is in the range 7-200 nm for a total thickness of 3 μm. The period's control of the nanoscaled hard films is achieved, a priori, ...
