摘要： OLED devices are disclosed having increased external electroluminescence quantum efficiencies, i.e., increased “out-coupling” efficiencies. OLED devices that have increased out-coupling efficiencies and that are also protected from environmental elements such as moisture and oxygen are also disclosed. The OLED device of the present invention comprises a substrate; an active region positioned on the substrate, wherein the active region comprises an anode layer, a cathode layer and a light-emitting layer disposed between the anode layer and the cathode layer; and a polymeric layer disposed (a) over the active region, (b) under the active region or (c) both over and under the active region. The polymeric layer has microparticles incorporated therein, and the microparticles are effective to increase the out-coupling efficiency of the OLED. In one embodiment, the OLED device comprises a composite barrier layer and the microparticles are incorporated in a polymeric planarizing sublayer of the composite barrier layer. The composite barrier layer in this embodiment also protects the OLED from damage caused by environmental elements such as moisture and/or oxygen.

摘要： A novel memory cell is provided with an active region including a molecular system and ionic complexes distributed in the molecular system. A pair of write electrodes are arranged for writing information to the memory cell. The active region is responsive to an electric field applied between the pair of write electrodes for switching between an on state and an off state. The active region has a high impedance in the off state and a low impedance in the on state. A pair of read electrodes is used to detect whether the active region is in the on state or in the off state to read the information from the memory cell. Read electrodes may be made of different materials having different work functions to reduce leakage current.

摘要： A multicolor organic light emitting device employs vertically stacked layers of double heterostructure devices which are fabricated from organic compounds. The vertical stacked structure is formed on a glass base having a transparent coating of ITO or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices, each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack. This constitutes the device emitting red light on the top with the device having the shortest wavelength, namely, the device emitting blue light, on the bottom of the stack. Located between the red and blue device structures is the green device structure. The devices are configured as stacked to provide a staircase profile whereby each device is separated from the other by a thin transparent conductive contact layer to enable light emanating from each of the devices to pass through the semitransparent contacts and through the lower device structures while further enabling each of the devices to receive a selective bias. The devices are substantially transparent when de-energized, making them useful for heads-up display applications.

摘要： This application relates to a method of depositing a patterned layer of material, such as organic material, over a substrate or organizing materials over a substrate. The method involves using a stamp having at least one conductive pathway and an insulating layer to transfer material from a solution to a substrate in a specified pattern. The stamp may be used multiple times to transfer a similar pattern of organic material to multiple substrates or to different portions of the same substrate. The transferred material may then be preferably used as a photolithographic mask for nano-patterning the substrate. This application also relates to a stamp that may be used in depositing a patterned layer of material onto a substrate, a method of forming such a stamp, and a method of depositing a layer of oriented molecules over a substrate.
