摘要： An OLED may include regions of a material having a refractive index less than that of the substrate, or of the organic region, allowing for emitted light in a waveguide mode to be extracted into air. These regions can be placed adjacent to the emissive regions of an OLED in a direction parallel to the electrodes. The substrate may also be given a nonstandard shape to further improve the conversion of waveguide mode and/or glass mode light to air mode. The outcoupling efficiency of such a device may be up to two to three times the efficiency of a standard OLED. Methods for fabricating such a transparent or top-emitting OLED is also provided.

摘要： An elastomeric stamp is used to deposit material on a non-planar substrate. A vacuum mold is used to deform the elastomeric stamp and pressure is applied to transfer material from the stamp to the substrate. By decreasing the vacuum applied by the vacuum mold, the elasticity of the stamp may be used to apply this pressure. Pressure also may be applied by applying a force to the substrate and/or the stamp. The use of an elastomeric stamp allows for patterned layers to be deposited on a non-planar substrate with reduced chance of damage to the patterned layer.

摘要： A microfluidic device for use with a microfluidic delivery system, such as an organic vapor jet printing device, includes a glass layer that is directly bonded to a microfabricated die and a metal plate via a double anodic bond. The double anodic bond is formed by forming a first anodic bond at an interface of the microfabricated die and the glass layer, and forming a second anodic bond at an interface of the metal plate and the glass layer, where the second anodic bond is formed using a voltage that is lower than the voltage used to form the first anodic bond. The second anodic bond is formed with the polarity of the voltage reversed with respect to the glass layer and the formation of the first anodic bond. The metal plate includes attachment features that allow removal of the microfluidic device from a fixture.

摘要： An organic semiconductor device is provided. The device has a first electrode and a second electrode, with an organic semiconductor layer disposed between the first and second electrodes. An electrically conductive grid is disposed within the organic semiconductor layer, which has openings in which the organic semiconductor layer is present. At least one insulating layer is disposed adjacent to the electrically conductive grid, preferably such that the electrically conductive grid is completely separated from the organic semiconductor layer by the insulating layer. Methods of fabricating the device, and the electrically conductive grid in particular, are also provided. In one method, openings are formed in an electrically conductive layer with a patterned die, which is then removed. In another method, an electrically conductive layer and a first insulating layer are etched through the mask to expose portions of a first electrode. In yet another method, a patterned die is pressed into a first organic semiconductor layer to create texture in the surface of the first organic semiconductor layer, and then removed. An electrically conductive material is then deposited onto the first organic semiconductor layer from an angle to form a grid having openings as a result of the textured surface and the angular deposition. In each of the methods, insulating layers are preferably deposited or otherwise formed during the process to completely separate the electrically conductive layer from previously and subsequently deposited organic semiconductor layers.

摘要： A device is provided having a first electrode, a second electrode, a first photoactive region having a characteristic absorption wavelength λ1 and a second photoactive region having a characteristic absorption wavelength λ2. The photoactive regions are disposed between the first and second electrodes, and further positioned on the same side of a reflective layer, such that the first photoactive region is closer to the reflective layer than the second photoactive region. The materials comprising the photoactive regions may be selected such that λ1 is at least about 10% different from λ2. The device may further comprise an exciton blocking layer disposed adjacent to and in direct contact with the organic acceptor material of each photoactive region, wherein the LUMO of each exciton blocking layer other than that closest to the cathode is not more than about 0.3 eV greater than the LUMO of the acceptor material.
