    摘要: Apparatus and method for plasma deposition of thin film photovoltaic materials at microwave frequencies. The apparatus avoids deposition on windows or other microwave transmission elements that couple microwave energy to deposition species. The apparatus includes a microwave applicator with conduits passing therethrough that carry deposition species. The applicator transfers microwave energy to the deposition species to transform them to a reactive state conducive to formation of a thin film material. The conduits physically isolate deposition species that would react to form a thin film material at the point of microwave power transfer. The deposition species are separately energized and swept away from the point of power transfer to prevent thin film deposition. The invention allows for the ultrafast formation of silicon-containing amorphous semiconductors that exhibit high mobility, low porosity, little or no Staebler-Wronski degradation, and low defect concentration.

    摘要: Devices are provided for separating and focusing analytes, comprising a separation chamber and electrodes separated from the separation chamber by a membrane. The electrodes are operative to generate an electric field in the separation chamber. Molecular sieve in the separation chamber is operative to shift the location at which a stationary focused band of the analyte forms under a given set of focusing process parameters. Methods are provided for separating and focusing charged analytes, comprising introducing a first fluid comprising at least one charged analyte into the separation chamber of a device as just described, applying an electric field gradient to the separation chamber to focus the charged analyte at a location in the separation chamber. Methods are provided for separating and focusing un-charged (including inadequately charged) analytes, comprising introducing a fluid comprising at least the uncharged analyte and lipids, micelles and/or vesicles into the separation chamber of a device as just described, and applying an electric field gradient to the separation chamber to focus the analyte (in association with the lipids, micelles and/or vesicles) at a location in the separation chamber.
