Titanium dioxide is a cheap, chemically stable and non-toxic material. However its electrical properties are unstable and it is a modest semiconductor and a mediocre insulator. For several applications it would be interesting to make it either more insulat ...
Single crystals of layered semiconductors such as WS2 and MoS2 have already proven their efficiency as active elements in photovoltaic cells. Due to their high optical absorption coefficient in the visible range, these materials could be used in the form o ...
Thin films of tantalum oxynitride were prepared by reactive magnetron sputtering using a Ta target and N2 and O2 as reactive gases. The nitrogen flow was kept constant while the oxygen flow was pulsed periodically. The film composition evolves progressivel ...
Nanocryst. solar cells were made by incorporation of cis-dithiocyanato-bis(2,2'-bipyridyl-4,4'-dicarboxylate) ruthenium (II) into sputter deposited titanium oxide films. After a pyridine treatment, it was possible to achieve a photoelec. conversion efficie ...
The in-situ growth of PbZrxTi1-xO3 (PZT) and PbTiO3 (PT) thin films by reactive sputter deposition has been investigated for applications with silicon substrates. In-situ deposition from three simultaneously operating magnetron sources was applied. At the ...
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 ...
We report evidence for the reduction of long range lattice order caused by slight departures from the optimal growth temperature in fully doped (x≈0.9) YBa2Cu3O6+x films deposited by ion-beam sputtering on 〈001⟩ SrTiO3. We estimate the characterist ...
The microstructure and chemical composition of sputtered thin films are strongly correlated with the deposition conditions. In the present work, we report the investigation of the film composition by electron probe microanalysis and photoemission experimen ...
Intermetallic thin films of stoichiometric NiAl and Ni3Al have been deposited onto n-type silicon (100) and nickel (110) substrates using r.f.-magnetron co-sputtering. The morphology and crystal structure of the thin films have been studied by transmission ...
We present the fabrication and characterization of hybrid SPM probes with full platinum (Pt) cantilever and tip for biological SPM experiments. In recent years, SPM has shown its value in imaging and characterizing biological samples. Classic SPM sensors f ...
