摘要： An optoelectronic device comprising an optically active layer that includes a plurality of domes is presented. The plurality of domes is arrayed in two dimensions having a periodicity in each dimension that is less than or comparable with the shortest wavelength in a spectral range of interest. By virtue of the plurality of domes, the optoelectronic device achieves high performance. A solar cell having high energy-conversion efficiency, improved absorption over the spectral range of interest, and an improved acceptance angle is presented as an exemplary device.

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： 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.
