Abstract:
A thin film manipulation method comprising: wetting a textured surface of a thin film manipulator with a liquid, the textured surface comprising peaks separated by valleys, the liquid forming capillary bridges between the peaks of the textured surface; picking up a thin film by contacting the thin film with the wetted textured surface to adhere the thin film to the wetted textured surface by capillary action of the capillary bridges with the thin film; and releasing the adhered thin film from the thin film manipulator. Also disclosed is a thin film manipulator.
Abstract:
A method comprising: • growing a layer of channel material (1101), preferably graphene, on a growth wafer (1112) to form a channel member, the growth wafer comprising a layer of catalyst material (1111) separated from a carrier wafer (1112) by a layer of release material (1113), the catalyst material serving as a seed layer for growing the layer of channel material; • depositing a layer of polymeric material (1102) over the formed channel member to form a supporting substrate for the layers of catalyst and channel material; • etching the layer of release material (1113) to remove the release material (1113) and carrier wafer (1112); and • patterning the layer of catalyst material (1111) to form source and drain electrodes (1116) configured to enable a flow of electrical current through the channel member.
Abstract:
An apparatus includes a separator/electrolyte assembly (304); a first energy storage portion (304/306) disposed on a first surface of the separator/electrolyte assembly (304); a second energy storage portion (304/308) disposed on a second surface of the separator/electrolyte assembly (304); a first metallized piezoelectric film (310) disposed on the first energy storage portion (304/306); and a second metallized piezoelectric film (312) disposed on the second energy storage portion (304/308). When a force is applied to the first metallized piezoelectric film (310), a piezoelectric effect converts mechanical strain into electric potential and each energy storage portion stores the energy converted in the first energy storage portion (304/306) and the second energy storage portion (304/308) for subsequent discharge from the first energy storage portion (304/306) and the second energy storage portion (304/308) to an electronic device.
