Characterization of a hydrogenated amorphous silicon microbolometer array
(2012-12-17)
We present the characterization of a boron doped hydrogenated amorphous silicon (a-Si:H) thermosensor bolometer
array for far infrared detection. The array was fabricated over a silicon wafer on a 0.4 μm silicon-nitride ...
Photoluminescence at room temperature in amorphous SrTiO3 thin films obtained by chemical solution deposition
(Elsevier B.V., 2003-01-15)
Intense photoluminescence in highly disordered strontium titanate amorphous thin films prepared by the polymeric precursor method was observed at room temperature (300 K). The luminescence spectra of SrTiO3 amorphous thin ...
Crystallization at room temperature from amorphous to trigonal selenium as a byproduct of the synthesis of water dispersible zinc selenide
(Elsevier B.V., 2012-11-15)
Zinc selenide is a semiconductor material that has been synthesized in aqueous media. However, this synthesis can yield some byproducts, which has been little exploited in literature of this area; one of these byproducts ...

Corrosion properties of Fe-Cr-Nb-B amorphous alloys and coatings
(Elsevier B.V., 2014-09-15)
In the present work, we report on the corrosion properties of the Fe60Cr8Nb8B24 (at.%) alloy produced using pure and commercial materials in the following conditions: amorphous ribbons, partially crystallized ribbons and ...
Heterogeneous Water Oxidation: Surface Activity versus Amorphization Activation in Cobalt Phosphate Catalysts
(2015)
Is water oxidation catalyzed at the surface or within the bulk volume of solid oxide materials? This question is addressed for cobalt phosphate catalysts deposited on inert electrodes, namely crystallites of pakhomovskyite ...
Amorphization and nanocrystallization of silicon under shock compression
(Pergamon-Elsevier Science Ltd, 2016-01)
High-power, short-duration, laser-driven, shock compression and recovery experiments on [001] silicon unveiled remarkable structural changes above a pressure threshold. Two distinct amorphous regions were identified: (a) ...
Short-range order in bulk Zr- and Hf-based amorphous alloys
(Elsevier Science Sa, 2000-02)
The local order in mechanically alloyed Hf65Al7.5Cu17.5Ni10 and Zr65Al7.5Cu17.5Ni10 amorphous alloys was studied by means of perturbed angular correlation measurements. The amorphous state of the starting material was ...
Influence of microstructure and hydrogen concentration on amorphous silicon crystallization
(Elsevier Science Sa, 2010-07)
Hydrogenated amorphous silicon samples were deposited on glass substrates at different temperatures by high 20 frequency plasma-enhanced chemical vapor deposition. In this way, samples with different hydrogen 21 concentrations ...
