Inert gas assisted cluster deposition of copper

Deposition of Size-Selected Cu Nanoparticles by Inert Gas Condensation

Nanometer size-selected Cu clusters in the size range of 1-5 nm have been produced by a plasma-gas-condensation-type cluster deposition apparatus, which combines a grow-discharge sputtering with an inert gas condensation technique. With this method, by controlling the experimental conditions, it was possible to produce nanoparticles with a strict control in size. The structure and size of Cu na...

Structure-property Interaction in Flux Assisted Tungsten Inert Gas Welding of Austenitic Stainless Steel

Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...

Characteristics of Conductive Ink Using Octanethiolated Copper Nanoparticles Produced via Inert-gas Condensation

Mechanisms of inert gas impact induced interlayer mixing in metal multilayers grown by sputter deposition

Control of interfacial roughness and chemical mixing is critical in nanomaterials. For example, multilayers composed of ;20 Å conductive layer sandwiched between two ;50 Å ferromagnetic layers can exhibit giant magnetoresistance ~GMR!. This property has caused a tremendous recent increase in hard disk storage capacity, and can potentially result in a new generation of nonvolatile magnetic rando...

Gas-assisted silver deposition with a focused electron beam

Focused electron beam induced deposition (FEBID) is a flexible direct-write method to obtain defined structures with a high lateral resolution. In order to use this technique in application fields such as plasmonics, suitable precursors which allow the deposition of desired materials have to be identified. Well known for its plasmonic properties, silver represents an interesting candidate for F...
