Oxide Thin Films Fabricated with Metal Alkoxides as Oxygen Sources

Metal oxide thin films as sensing layers for ozone detection.

In2O3-x thin films with a thickness of 100-990 nm were grown by dc magnetron sputtering. Their structural, electrical and ozone sensing properties were analyzed. Structural investigations carried out by electron probe micro analysis, secondary ion mass spectrometry and atomic force microscopy showed a strong correlation between stoichiometry, surface topology and gas sensitivity. Moreover, the ...

Chiral thin films of metal oxide.

In this paper, we describe for the first time the synthesis of new chiral nanosized metal oxide surfaces based on chiral self-assembled monolayers (SAMs) coated with metal oxide (TiO2) nanolayers. In this new type of nanosize chiral surface, the metal oxide nanolayers enable the protection of the chiral self-assembled monolayers while preserving their enantioselective nature. The chiral nature ...

Metal Oxide Thin Films and Nanostructures Made by ALD

Colloidal synthesis of metal oxide nanocrystals and thin films

A main driving force behind the recent years’ immense interest in nanoscience and nanotechnology is the possibility of achieving new material properties and functionalities within, e.g., material physics, biomedicine, sensor technology, chemical catalysis, energy storing systems, and so on. New (theoretical) possibilities represent, in turn, a challenging task for chemists and physicists. An im...

Metal–oxide bilayer Raman scattering in SrTiO3 thin films

We have used a metal–oxide bilayer Raman scattering technique to study lattice dynamics in SrTiO3 thin films. The SrTiO3 thin films were epitaxially grown on a conducting metal–oxide layer which reflects the exciting laser beam so that it does not enter the LaAlO3 substrate. Raman scattering from the SrTiO3 thin films was clearly observed, including the first-order Raman peaks forbidden by the ...
