Studium plasmy v hybridním PLD systému pro přípravu CN.sub.x./sub. vrstev
Novotný, Michal ; Jelínek, Miroslav ; Bulíř, Jiří ; Lančok, Ján ; Zelinger, Zdeněk
We have developed hybrid PLD systems (combination of PLD and additional radiofrquency discharges) for increasing active nitrogen concentration in plasma and consequently N/C ratio in deposited films. For study of plasma and plasma processes we have used OES
Luminiscenční vlastnosti Er:YAG a Er:YAP tenkých vrstev připravených pulsní laserovou ablací
Pavelka, Martin ; Jelínek, Miroslav ; Lančok, Ján ; Oswald, Jiří
Luminescence properties of Er:YAG and Er:YAP thin films were studied and the possibilities of creation of planar waveguide lasers were investigated
Pulsní laserová depozice homogenních DLC vrstev
Kocourek, Tomáš ; Jelínek, Miroslav ; Lančok, Ján ; Bulíř, Jiří
The goal of the experiment is to achive a homogenous thickness profile of DLC films on the substrate of dimension of 30 mm in diameter. Such layers can be used to cover artificial heart valves - DLC is a bio-inert material
Waveguiding ZnO and BaTiO3 thin films fabricated by laser deposition
Jelínek, Miroslav ; Kocourek, Tomáš ; Mazingue, T. ; Escoubas, L. ; Flory, F.
Various deposition configurations for deposition of large area homogenous films (3x3c 2 ) were studied. High quality ZnO and BaTiO3 films were deposited by KrF laser ablation. Optical properties by method of mode spectroscopy were measured.
Nanokrystalické diamantové vrstvy deponované hybridní pulsní laserovou depozicí
Novotný, Michal ; Jelínek, Miroslav ; Bulíř, Jiří ; Lančok, Ján ; Vorlíček, Vladimír
We used pulsed laser deposition (PLD) and hybrid PLD (HPLD) techniques for NCD thin films preparation. KrF excimer laser beam (Lumonics, .lambda.=248 nm , 20 ns, 500 mJ) was focused on graphite target with energy density of 4-7 J.cm.sup.- 2./sup.. Films were deposited on sapphire and Si(100) substrates in hydrogen and argon/hydrogen ambient
Vliv RF výboje na růst nanokrystalických diamantových vrstev deponovaných metodou pulsní laserové depozice
Novotný, Michal ; Jelínek, Miroslav ; Bulíř, Jiří ; Lančok, Ján ; Vorlíček, Vladimír ; Michalka, M. ; Popov, C.
In this paper, we report on the growth of NCD films by PLD in pure hydrogen ambient and by HPLD in Ar/H.sub.2./sub. ambient. HPLD systems were based on combination of PLD and addiational RF discharges. The deposited films were studied using Alfastep profilometer, X-ray diffraction, Raman spectroscopy and scanning electron microscopy
Nanokrystalické diamant/amorfní uhlík kompozitní vrstvy připraveny MWCVD
Popov, C. ; Kulisch, W. ; Boycheva, S. ; Jelínek, Miroslav
The aim of the present work was to prepare nanocomposite films in which both phases are composed of only one element - carbon, i.e. nanosized diamond crystallites embeded in an amorphous carbon matrix. In our study, emphasis was laid on the investigation of both the crystalline(e.g. crystallite size) and the amorphous (e.g. sp.sup.3./sup./sp.sup.2./sup. ratio, H content) fractions of these new nanocomposite films
Nanogranulární vrstvy Co-Al-O připravené laserovou ablací
Chayka, Oleksandr ; Kraus, Luděk ; Fendrych, František ; Kocourek, Tomáš ; Jelínek, Miroslav
The measurements of magnetic and transport properties of the films deposited by laser ablation show that the films prepared on room temperature substrates consist of single-domain nanosized Co particles embeded in an insulating matrix.The films deposited on heated substrates show two orders lower resistance and their MR is one order smaller. This can be explained by the appearance of metallic type conductivity in a network of particles that is presumably due to coalescence of the grains
