    摘要： There is disclosed a thin film device for epitaxial lift off comprising a handle and one or more straining layers disposed on the handle, wherein the one or more straining layers induce a curvature of the handle. There is also disclosed a method of fabricating a thin film device for epitaxial lift off comprising, depositing one or more straining layers on a handle, wherein the one or more straining layers induce at least one strain on the handle chosen from tensile strain, compressive strain and near-neutral strain. There is also disclosed a method for epitaxial lift off comprising, depositing an epilayer over a sacrificial layer disposed on a growth substrate; depositing one or more straining layers on at least one of the growth substrate and a handle; bonding the handle to the growth substrate; and etching the sacrificial layer.

    摘要： A solder joint may be used to attach components of an organic vapor jet printing device together with a fluid-tight seal that is capable of performance at high temperatures. The solder joint includes one or more metals that are deposited over opposing component surfaces, such as an inlet side of a nozzle plate and/or an outlet side of a mounting plate. The components are pressed together to form the solder joint. Two or more of the deposited metals may be capable of together forming a eutectic alloy, and the solder joint may be formed by heating the deposited metals to a temperature above the melting point of the eutectic alloy. A diffusion barrier layer and an adhesion layer may be included between the solder joint and each of the components.

    摘要： A method for fabricating an organic photovoltaic cell includes providing a first electrode; depositing a series of at least seven layers onto the first electrode, each layer consisting essentially of a different organic semiconductor material, the organic semiconductor material of at least an intermediate layer of the sequence being a photoconductive material; and depositing a second electrode onto the sequence of at least seven layers. One of the first electrode and the second electrode is an anode and the other is a cathode. The organic semiconductor materials of the series of at least seven layers are arranged to provide a sequence of decreasing lowest unoccupied molecular orbitals (LUMOs) and a sequence of decreasing highest occupied molecular orbitals (HOMOs) across the series from the anode to the cathode.

    摘要： An organic optoelectronic device (OED) includes a plurality of OED cells separated by a vapor flow barrier that extends away from a substrate surface. The vapor flow barrier partially defines an OED cell area and helps prevent stray organic material deflected away from the substrate surface during deposition from being deposited outside the cell area. An organic vapor jet (OVJ) print head can be used to deposit organic material along the vapor flow barrier and may include one or more features configured to capture some of the stray organic material. A method that includes use of vapor flow barriers and/or capturing stray organic material can facilitate high-density printing of OED cells such as OLEDs with sharply defined edges and without cross-contamination among adjacent cells.
