Understanding the growth mechanism in molecular organic thin films is fundamental to their applications in organic electronics. We present an extensive study of the growth mechanism of pentacene thin films on silicon dioxide (SiO2) using atomic ...
Due to their high hardness, high melting point and high chemical stability, transition metal nitrides present a great interest for various applications. This work constitutes a contribution to the understanding of the properties of Nb based binary and tern ...
Using a density-functional framework, we investigate the vibrational spectra of vitreous SiO2 to determine to what extent these spectra provide information about the medium-range structure of the oxide network. We carry out a comparative study involving th ...
everal SrTiO3 (STO) thin films without electrodes processed by pulsed laser deposition, of thicknesses down to 40 nm, were studied using infrared transmission and reflection spectroscopy. The complex dielectric responses of polar phonon modes, particularly ...
The exact mechanism of creep resistance enhancement due to yttrium (Y) doping in a-alumina is still subject to speculation, although it is known that dopants segregate strongly to grain boundaries. The current work applies atomistic simulation techniques t ...
This is the first part of the two articles reporting investigation of a thermal detector-type far-infrared sensor operating in the 8–14µm wavelength, using Low-Pressure-Chemical-Vapor-Deposition (LPCVD)- deposited low-stress Si-rich nitride (SiN)membrane a ...
Despite many years of intensive research there still remain many unresolved questions in powder and ceramic technology. A majority of these issues are linked to interfacial phenomena of atomic scale origin, which makes their experimental investigation very ...
High temperature plasticity of fine-grained ceramics (ZrO2, Al2O3, etc) is usually associated with a grain boundary sliding process. The aim of the present research is then to improve the high-temperature mechanical strength of polycrystalline zirconia (3Y ...

A comprehensive model for the electronic transport in polycrystalline ZnO:B thin films grown by low pressure chemical vapor deposition is presented. The optical mobilities and carrier concentration calculated from reflectance spectra using the Drude model ...
Titanium aluminium nitride (TiAlN)-based coatings are designed specially for applications where oxidation and wear resistance are primary demands, as in the case of cutting tools. Moreover the coatings are required to be thermally stable as well as have go ...
