Cluster calculations employing hybrid density functional theory have been carried out to examine the initial surface reactions in atomic layer deposition (ALD) of TiN thin films on the SiO2 surface using TiCl4 and NH3 as precursors. The potential energy su ...
One embodiment of this invention relates to a substrate (3) having a crystalline tin (IV) oxide film grown thereon, the film comprising a plurality of nanorods each of hick includes crystals grown along the c-axis of the tin (IV) oxide crystal. Another emb ...
We investigate heterojunction photovoltaic devices using the carbocyanine 1,1'-diethyl-3,3,3',3'-tetramethylcarbocyanine perchlorate (Cy5) as donor and buckminsterfullerene (C60) as acceptor. We find that photocurrent generation occurs at the in ...
A method for a binder-free manufg. a nanostructured porous film, e.g. for use in solar cells, includes the steps of prepg. a suspension of semiconducting nanoparticles in a volatile suspension agent, depositing the particle suspension on a conducting subst ...
TiO2/ITO modified electrodes were developed to quantitatively photooxidize adsorbed ds-DNA and to study the effect of antioxidants as ds-DNA protecting agents. TiO2 films are used for efficient ds-DNA immobilization, for ds- DNA oxidation through photogene ...
Because of their outstanding mechanical and chemical properties, transition metal nitrides are widely accepted materials in the protective coatings industry. This work aims at elucidating the origin of their exceptional properties. The study concentrates o ...
The aim of this paper is to present a novel approach to pattern silicon nanowires for advanced electronics applications. A simple non-lithographic process was successfully developed to define sub-40nm diameter silicon wires and to connect them to test pads ...
We present a technology for the fabrication of three dimensional microfluidic channels in optically transparent substrates consisting of polymers with different properties. The microstructures are fabricated using polymer replication techniques with a view ...
Zinc oxide (ZnO) is now often used as a transparent conductive oxide for contacts in thin-film silicon solar cells. This paper presents a study of ZnO material deposited by the low-pressure chemical vapour deposition technique, in a pressure range below th ...
The mechanical properties of ultrathin silicon oxide (SiOx ) coatings plasma-deposited on poly(ethylene terephthalate) (PET) films were investigated with particular attention paid to the effect of additives located in the superficial layers of the polymer ...
