Thin film deposition via a spatially-coordinated and time-synchronized process

A deposition system and process for the formation of thin film materials. In one embodiment, the process includes forming an initial plasma from a first material stream and allowing the plasma to evolve in space and/or time to extinguish species that are detrimental to the quality of the thin film material. After the initial plasma evolves to an optimum state, a second material stream is injected into the deposition chamber to form a composite plasma that contains a distribution of species more conducive to formation of a high quality thin film material. The deposition system includes a deposition chamber having a plurality of delivery points for injecting two or more streams (source materials or carrier gases) into a plasma region. The delivery points are staggered in space to permit an upstream plasma formed from a first material stream deposition source material to evolve before combining a downstream material stream with the plasma. Injection of different material streams is also synchronized in time. The net effect of spatial coordination and time synchronization of material streams is a plasma whose distribution of species is optimized for the deposition of a thin film photovoltaic material at high deposition rates. Delivery devices include nozzles and remote plasma sources.

Molybdenum disulfide nano-sheet film material and its preparation methods

The invention discloses a molybdenum disulfide (MoS2) nano-sheet film material and its preparation methods. The film material is characterized in that MoS2 nano-sheets vertically and sequentially grow on a conductive substrate, and the diameters and the thicknesses of the MoS2 nano-sheets are 0.05-2mum and 2-30nm respectively. There are two preparation methods of the film material. One preparation method comprises the following steps: a substrate which can be a copper sheet, a silver sheet, a titanium sheet, a tungsten sheet, a molybdenum sheet or carbon is placed in a solution comprising a molybdate and sulfur-containing compounds (comprising thiourea, thioacetamide and L-cysteine); and the sulfur-containing compounds undergo a hydrothermal reaction to grow the compactly-grown and uniformly-sequential MoS2 nano-sheet films on the substrate. Another method comprises the following steps: the molybdenum sheet is directly placed in a solution of the sulfur-containing compounds (comprising thiourea, thioacetamide and L-cysteine); and the sulfur-containing compounds undergo a sulfuration reaction under a hydrothermal condition to form the compact and uniform MoS2 nano-sheet ordered films. The film has a low hydrogen evolution overpotential (-30mv), a small Tafel slope (52mV/dec) and a high electrochemical stability, and is a hydrogen evolution electrode material extremely having an application prospect.

Self-supporting laminated films, structural materials and medical devices manufactured therefrom and methods of making same

Metal foils, wires, and seamless tubes with increased mechanical strength are provided. As opposed to wrought materials that are made of a single metal or alloy, these materials are made of two or more layers forming a laminate structure. Laminate structures are known to increase mechanical strength of sheet materials such as wood and paper products and are used in the area of thin films to increase film hardness, as well as toughness. Laminate metal foils have not been used or developed because the standard metal forming technologies, such as rolling and extrusion, for example, do not lend themselves to the production of laminate structures. Vacuum deposition technologies can be developed to yield laminate metal structures with improved mechanical properties. In addition, laminate structures can be designed to provide special qualities by including layers that have special properties such as superelasticity, shape memory, radio-opacity, corrosion resistance etc. Examples of articles which may be made by the inventive laminate structures include implantable medical devices that are fabricated from the laminated deposited films and which present a blood or body fluid and tissue contact surface that has controlled heterogeneities in material constitution. An endoluminal stent-graft and web-stent that is made of a laminated film material deposited and etched into regions of structural members and web regions subtending interstitial regions between the structural members. An endoluminal graft is also provided which is made of a biocompatible metal or metal-like material. The endoluminal stent-graft is characterized by having controlled heterogeneities in the stent material along the blood flow surface of the stent and the method of fabricating the stent using vacuum deposition methods.
