TLDR
In this article, the authors have succeeded to fabricate a thin film consisting of nano-crystallites TiO on a substrate at room temperature by using the magnetron sputtering combined with the gas aggregation method which has the capability to deposit grown small particles and/or clusters of the desired compound material on the substrate in soft-landed mode.Abstract:
We have succeeded to fabricate the thin film mainly or entirely consisting of nano-crystallites TiO on a substrate at room temperature by using the magnetron sputtering combined with the gas aggregation method which has the capability to deposit grown small particles and/or clusters of the desired compound material on the substrate in soft-landed mode. The important experimental parameters to control the growth of TiO particles are identified as partial pressure of additional oxygen gas, growth-reaction distance Ltd, and LN2 cooling of growth chamber. The smallest averaged diameter of TiO nano-particles is 5.62 nm and size distribution being from 2 to 8 nm under 50 mm of Ltd. The compositional uniformity is confirmed by EDS and EELS. The chemical state of the film observed by Ti 2P XPS peak confirms the primarily growth of TiO and indicates the formation of minor content of amorphous Ti1-xOx and/or Ti1-xCx particularly at the surface of the film.read more

Sputter deposition of titanium monoxide and dioxide thin films with controlled properties using optical emission spectroscopy
TL;DR: In this article, optical emission spectroscopy was employed to monitor the intensity of Ti emission lines via a flow-supply feedback loop, which allowed the process windows along the metallic-poisoned curve to be found for the controlled deposition of TiOx thin films, particularly titanium monoxide and oxides with the values of x in the vicinity of 2.0.

Electron spectroscopy imaging and surface defect configuration of zinc oxide nanostructures under different annealing ambient
TL;DR: In this paper, electron spectroscopy imaging was used to visualize the elemental distribution of zinc oxide nanopowder, and surface modification in zinc oxide was done through annealing treatment and type of surface defect was also inferred from the X-ray imaging investigation.

TL;DR: Low-loss images reveal morphological details of thick aggregates made out of colloidal polymers and inorganic particles at a spatial resolution close to that achieved in the bright-field images and much better than in the elemental maps, showing the advantages of the simultaneous use of low- Loss images and standard thin-cut elemental maps.

Optical properties of nanometric TiO2 clusters deposited on thin films by high pressure sputtering
TL;DR: In this article, a magnetron sputtering source placed inside a high pressure aggregation chamber was used to produce fine particles from a target material through sputtering after cluster aggregation inside a 10 − 1 ǫm (He/Ar) gas atmosphere.

A new type of cluster and cluster ion source
TL;DR: Combining a magnetron gas discharge with the gas aggregation technique, an intense source of clusters has been developed as discussed by the authors, where a large part (up to 80%) of the clusters can be generated as ions without using additional electron impact ionisation.
