Reactively sputtered Ni, Ni(N) and Ni3N films: Structural, electrical and magnetic properties
(Applied Surface Science, 2009)
Nickel thin films were deposited on glass substrates at different N-2 gas contents using a dc triode sputtering deposition system. Triode configuration was used to deposit nanostructured thin films with preferred orientation ...
Surface modifications of TiN coating by pulsed TEA CO2 and XeCl lasers
(Applied Surface Science, 2005)
Interactions of a transversely excited atmospheric (TEA) CO2 laser and an excimer XeCl laser, pulse durations similar to 2 mu s (initial spike FWHM similar to 100 ns) and similar to 20 ns (FWHM), respectively, with ...
Surface modification of stainless steels by TEA CO2 laser
(Applied Surface Science, 2001)
The interaction of a transversely excited atmospheric (TEA) CO2 laser with austenitic stainless AISI 316 and high-speed tool AISI M2 steel is considered. The results have shown that both types of steel were surface modified ...
Pulsed TEA CO2 laser surface modifications of silicon
(Applied Surface Science, 2003)
The interaction of a transversely excited atmospheric (TEA) CO, laser, pulse duration of about 2 mus (FWHM of initial spike = 120 ns), with p-type single crystalline silicon doped by boron, was studied. The results have ...
Effects of O2+ ions beam irradiation on crystal structure of rare earth sesquioxides
(Applied Surface Science, 2009)
We report the results of ion irradiation influence on rare earth sesquioxides structure, which are materials of practical importance as a radiation resistant ceramics in nuclear applications. Y2O3, Gd2O3 and Er2O3 sesquioxides ...
Surface analysis of the nanostructured W-Ti thin film deposited on silicon
(Applied Surface Science, 2007)
The W-Ti thin films are deposited by the dc Ar+ sputtering of W(70%)-Ti(30%) a.t. target on silicon substrates. The surface composition and structure of the thin film, previously exposed to air, was carded out. The surface ...
Diamond coating deposition by synergy of thermal and laser methods - A problem revisited
(Applied Surface Science, 2007)
Diamond coatings were deposited by synergy of the hot filament CVD method and the pulse TEA CO2 laser, in spectroactive and spectroinactive diamond precursor atmospheres. Resulting diamond coatings are interpreted relying ...
Surface modifications of a titanium implant by a picosecond Nd : YAG laser operating at 1064 and 532 nm
(Applied Surface Science, 2006)
Interaction of an Nd:YAG laser, operating at 1064 or 532 nm wavelength and pulse duration of 40 ps, with titanium implant was studied. Surface damage thresholds were estimated to 0.9 and 0.6 J/cm(2) at wavelengths 1064 and ...
Surface modifications of crystalline silicon created by high intensity 1064 nm picosecond Nd : YAG laser pulses
(Applied Surface Science, 2007)
A study of silicon modification induced by a high intensity picosecond Nd:YAG laser, emitting at 1064 nm, is presented. It is shown that laser intensities in the range of 5 x 10(10)-0.7 x 10(12) W cm(-2) drastically modified ...
Periodic surface structures on crystalline silicon created by 532 nm picosecond Nd : YAG laser pulses
(Applied Surface Science, 2007)
Creation of laser-induced morphology features, particularly laser-induced periodic surface structures (LIPSS), by a 532 nm picosecond Nd:YAG laser on crystalline silicon is reported. The LIPSS, often termed ripples,. were ...
