摘要: The current invention provides a method of fabricating nano-pore structured dense Pt electrodes using particle masking and LB deposition methods. The pore size and TPB density are easily tunable by changing initial size of the masking silica particles and the spacing between them. Compared to the solid oxide fuel cell MEAs with porous Pt electrode deposited by conventional DC sputtering method, fuel cell MEAs with the nano structured electrodes fabricated according to the current invention showed thermal and microstructural stability and superior I-V performance at 400˜450° C. Also, EIS spectra showed significant improvement in the oxygen reduction kinetics by increasing the density of charge transfer sites at the TPB. A nearly linear scaling relationship between TPB density and fuel cell performance was also demonstrated.

摘要: A variety of methods, devices, systems and arrangements are implemented involving nanowire meshes. One such method is implemented to include synthesizing metal nanowires in a solution containing a structure-directing agent. The metal nanowires are deposited on a substrate to form a sheet of nanowires. The deposited metal nanowires are heated to a temperature less than about 200 degrees Celsius and for a period of time of about 10 minutes to 60 minutes, thereby removing the structure-directing agent and modifying the electrical conductivity and optical transmittance of the sheet of nanowires.

摘要: Embodiments of the disclosure generally provide methods of forming a silicon containing layers in TFT devices. The silicon can be used to form the active channel in a LTPS TFT or be utilized as an element in a gate dielectric layer, a passivation layer or even an etch stop layer. The silicon containing layer is deposited by a vapor deposition process whereby an inert gas, such as argon, is introduced along with the silicon precursor. The inert gas functions to drive out weak, dangling silicon-hydrogen bonds or silicon-silicon bonds so that strong silicon-silicon or silicon-oxygen bonds remain to form a substantially hydrogen free silicon containing layer.
