Ion Implantation Induced Modifications in Reactively Sputtered Cr-N Layers on Si Substrates
(Materials Science Forum, 2007)
We present a study of the micro-structural changes induced in Cr-N layers by irradiation with argon ions. The layers were deposited by reactive ion sputtering on (100) Si wafers, to a thickness of 240-280 nm, at different ...
Ion beam assisted deposition of TiN thin films on Si substrate
(Materials Science Forum, 2006)
In this paper we present a study of the formation of TiN thin films during the IBAD process. We have analyzed the effects of process parameters such as Ar+ ion energy, ion incident angle, Ti evaporation rates and partial ...
Far-infrared phonon spectroscopy of Cd1-xMnxS quantum dots
(Materials Science Forum, 2004)
Phonon spectra of Cd1-xMnxS (x =0; 0.01; 0.05; 0.1; 0.15; 0.3) quantum dots (dsimilar to4.5 nm) are investigated by far-infrared reflection in the spectral range 80 - 600 cm(-1) and temperature range 80-300 K. The Cd1-xMnxS ...
SEM and XRD characterization of Ni-Hf alloys at low Hf concentration
(Materials Science Forum, 2006)
The alloying and phase formation in Ni-Hf samples with 0.2-, 2-, and 5-at.% Hf were studied by X-ray diffraction (XRD) technique and scanning electron microscopy (SEM). Both characterization methods, XRD and SEM, reveal ...
EPR study of manganese in Cd1-xMnxS quantum dots
(Materials Science Forum, 2004)
Cd1-xMnxS quantum dots (QDs) with a diameter d less than or equal to 4.5 nm and manganese concentration from x 0.001 to x 0.15 have been prepared using aqueous Solution precipitation. The EPR measurements have been performed ...
Spin interactions in Cd1-xMnxS bulk crystals
(Materials Science Forum, 2005)
Electron paramagnetic resonance (EPR) linewidth in the Cd1-xMnxS bulk crystals with manganese concentrations x = 0.25, 0.33, 0.35 and 0.42 has been studied in the high-temperature region. An analysis of the infinite-temperature ...
Electron paramagnetic resonance in Hg1-xMnxTe1-ySey
(Materials Science Forum, 2000)
Electron paramagnetic resonance has been studied in diluted magnetic semiconductor Hg1-xMnxTe1-ySey with y=0.01 and x=0.01, 0.03, 0.05, 0.14 and with y=0.075, x=0.14 in the temperature range 20-290 K. It is found that the ...
Optical and magnetic properties of Hg1-xMnxSe alloys
(Materials Science Forum, 2005)
In this paper we used X-ray, far-infrared reflectivity and electron paramagnetic resonance measurements to investigate the optical and magnetic properties of Hg1-xMnxSe (x LT = 0.26) alloys. Also, we used different models ...
Heteropolyacids as protonic conductors
(Materials Science Forum, 1996)
Protonic conductors belong to the conductors whose charge carriers are proton and protonic entities: H+, OH-, H2O, [H(H2O)(n)](+). A small group of these compounds have exceptionally high proton conductivity, Heteropolyacids ...
Structure, properties and application of Ni3Al aluminides
(Materials Science Forum, 1996)
Intermetallic compounds have long been recognized as potentially useful structural materials, Ni3Al aluminides possess excellent oxidation resistance at high temperatures as well as good high-temperature strength, This ...
