Excimer Laser Ablation is a micro-machining method which has undergone an important breakthrough in the last twenty years. In contrast with most literature studies, dealing with Static Ablation, this PhD work focuses on the study of Scanning Ablation of po ...
The electroosmotic flow in laminated excimer laser-ablated microchannels has been studied as a function of the depth of the rectangular channels, and particular emphasis has been given to the difference in the ζ-potentials between the lamination layer and ...
We discuss our systematic series of experiments on the photoelectric detection of the Fermi edge using a cylindrical mirror analyser on films of high-T-c oxides. grown in situ by pulsed laser ablation. The Fermi edge (comparable to the edge of the referenc ...
Crystalline diamond coatings and, increasingly, diamond-like amorphous carbon (DLC) films are used for tribological and protective layers for their hardness and chemical inertness. They are also under investigation for their electron emitting properties, w ...
We present measurements for the resistivity of `c' axis oriented YBa2Cu3O7-δ (YBCO) films grown on (100) SrTiO3 substrates by both laser ablation and ion beam sputtering. The effect of the magnetic field on the resistivity is investigated with the field pa ...
In YBa2Cu3O6+x the tetragonal to orthorhombic transition occurs around x equals 0.3, followed by a continuum variation of lattice parameters. Hence both, the structural and superconducting properties, depend upon the oxygen content in CuO chains. Conversel ...
Frequency doubled Nd:YAG lasers represent an attractive alternative to other laser tools for many material processing applications, but frequency doubling with pulsed Nd:YAG lasers has been performed until now only with pulses of tens of nanoseconds. In ma ...
We report on improved structural, crystallographic and electrical properties of epitaxial NdBa2Cu3O7-delta (NBCO) films grown on SrTiO3 by 'off-axis' pulsed laser deposition (PLD). Transport and XRD studies show that the c-axis-oriented epitaxial films, wi ...
