The nanoporous anodic alumina matrixes thickness of 1.5mm and pore sizes of 45, 90 and 145nm were formed on Si substrates. The tubular carbon nanostructures were synthesized into the matrixes pores by pyrolysis of fluid hydrocarbon xylene with 1% ferrocene. The structure and composition of the matrix coatings were examined by scanning electron microscopy, Auger analysis and Raman spectroscopy. The...
Method of nanoporous templates creating based on the anodic alumina (AA) for forming of quantum nanowires with a high aspect ratio is developed. The processes of InSb electrochemical deposition in the pores of templates are studied. The results of electron microscopic study of these nanostructures and electron probe electron probe X-ray spectrum microanalysis are shown. Percentage ratio of indium...
The process of formation of cold cathodes on the basis of carbon nanotubes synthesized in porous anodic alumina has been developed. Integral and local field emission (FE) measurements of produced cathodes have been performed. Main FE parameters: onset field, field enhancement factor and current capability of certain emitters have been measured.
Thin nanoporous alumina films were grown on n-type Si wafers by anodizing sputtered-deposited Al/Ti layers to prepare matrix of metal oxide catalysts with contact interface - Al2O3/TiO2/Ti/n-Si for later synthesis of carbon nanotubes (CNTpsilas) in the alumina pores. CNTpsilas were grown by CVD in the presence of ferrocene catalyst. Measurements of field emission properties of the CNTpsilas in anodic...
We propose a new cathode for organic light-emitting devices based on anodic porous alumina films. In these films, the bottom part of alumina layer, placed between the aluminium and pore space, is removed. The usage of porous alumina cathode results in more inhomogeneous electric field and, as a consequence, in more intensive auto-electron emission and higher cathode efficiency. Luminescent organic...
