Photoinduced Darkening and Bleaching in Amorphous As2S3 Thin Films
Munzar, Martin ; Tichý, Ladislav
Photodarkening significantly depends on the (the excitation light wavelength, the penetration depth of the excitation light, the incident photon flux and the number of absorbed photons in a sample.
Photoinduced changes of structure and properties of amorphous chalcogenides, description, interpretation
Frumar, M. ; Frumarová, Božena ; Wágner, T. ; Jedelský, J.
Changes of properties and structure of thin films of amorphous chalcogenides were disscused, a model proposed and possible applications described.
Study of microcrystalline silicon by combined AFM microscope
Mates, Tomáš ; Fejfar, Antonín ; Rezek, Bohuslav ; Fojtík, Petr ; Drbohlav, Ivo ; Luterová, Kateřina ; Pelant, Ivan ; Kočka, Jan
Recent results by combined AFM (topography and local conductivity) and correlation between microstructure and electrical properties of thin silicon films.
Galium-nitridové vrstvy dopované erbiem
Prajzler, V. ; Hüttel, I. ; Špirková, J. ; Schröfel, J. ; Machovič, V. ; Peřina, Vratislav
The paper describes the preparation and properties of gallium nitride layers with erbiu content.
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
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.
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
