Reaktivní magnetronové naprašování tenkých vrstev s unikálními vlastnostmi

Early transition metals and their oxides and nitrides are widely used in industrial applications due to their high hardness, thermal stability, transparency (in the case of oxides and some nitrides) and other unique combinations of properties. This PhD thesis is dedicated to the re...

Výsokovýkonové pulzní reaktivní magnetronové naprašování oxidových a oxynitridových vrstev

Transition metal oxides and oxynitrides are a class of materials with yet unexplored physical, chemical and functional properties, and a great potential for industrial applications. This Ph.D. thesis deals with preparation and characterization of multifunctional oxide and oxynitride films. They w...

Laser re-melting of tungsten damaged by transient heat loads

In the current study, a solid state disc laser with a wavelength of 1030 nm and maximum power of 5.3 kW was used to melt the surface of pure tungsten samples (manufactured according to ITER specifications by Plansee SE). Several combinations of laser power and traverse&#x...

Plazmonické vlastnosti naprášených Au nano-ostrůvkových polí

The specificity of the formation of Au sputtered nanoisland arrays (NIA) on a glass substrate or on a ZnO thin film doped by Ga is demonstrated. Statistical analysis of morphology images (SEM, AFM) exhibited the Log-normal distribution of the size (area) of nanoislands—their modus&...
