    摘要： A barrier for preventing water or oxygen from a source thereof from reaching a device that is sensitive to water or oxygen. The barrier is constructed by depositing a first polymer layer between the device and the source. An inorganic layer is deposited on the first polymer layer of the device by plasma enhanced chemical vapor deposition utilizing an electron cyclotron resonance source ECR-PECVD. A second polymer layer is then deposited on the inorganic layer. The inorganic layer is preferably an oxide or nitride. A second barrier layer having a compound that absorbs oxygen or water can be placed between the inorganic layer and the device to further retard the passage of oxygen or water. The present invention is particularly useful in encapsulating electroluminescent displays.

    摘要： A novel tunnel structure is described that enables tunnel diode behavior to be exhibited even in material systems in which extremely heavy doping is impossible and only moderate or light doping levels may be achieved. In one aspect, the tunnel heterostructure includes a first semiconductor layer, a second semiconductor layer, and an intermediate semiconductor layer that is sandwiched between the first and second semiconductor layers and forms first and second heterointerfaces respectively therewith. The first and second heterointerfaces are characterized by respective polarization charge regions that produce a polarization field across the intermediate semiconductor layer that promotes charge carrier tunneling through the intermediate semiconductor layer. In another aspect, the invention features a semiconductor structure having a p-type region, and the above-described heterostructure disposed as a tunnel contact between the p-type region of the semiconductor structure and an adjacent n-type region.

    摘要： A charge injection transistor is a real-space electron transfer heterostructure with several novel features. The channel layer is comprised of In.sub.0.25 Ga.sub.0.75 As supported by a buffer layer of Al.sub.0.3 Ga.sub.0.7 As resting on the substrate. A barrier layer comprised of Al.sub.0.1 Ga.sub.0.9 As overlays the channel layer. Over this barrier is a layer of GaAs forming the electron drift region. The collector electrode is located on top of this drift layer, between the source and heater electrodes, which extend downward through the drift and barrier layers and create the electric field in the channel layer. Positive voltages are applied to the heater and collector, relative to the source. Electrons flow through the channel region and become heated. At sufficiently high temperature they escape over the barrier and travel through the drift region to the collector. In comparison with previous devices, the use of InGaAs in the channel layer provides a deeper quantum well for the conduction electrons, and suppresses leakage through the barrier at room temperatures. The collector drift layer has a short transit time delay. The location of the collector reduces parasitic leakage from the source, and the collector capacitance is small. These features enhance the high frequency performance of the device. The limiting power gain frequency and current gain frequency are at least twice the corresponding values attained in previous devices.

    摘要： A device for a light detection system includes an electroluminescent layer stack on a transparent member, such as a glass substrate, with at least one layer of the layer stack being patterned to define first and second electroluminescent regions spaced apart by a transparent light collection path for passage of backreflected light. The layer stack includes first and second electrode layers on opposed sides of one or more active layers. In one embodiment, the second electrode layer is the only layer that is patterned to define the light collection path. In this embodiment, the other layers extend continuously across the light collection path. In another embodiment, all of the layers are patterned to form a gap between the first and second electroluminescent regions. The layer stack is hermetically sealed to protect the active layer or layers from atmosphere-induced degradation. An illumination collector is aligned with the light collection path to receive light that is backreflected from a surface of interest through the light collection path. The illumination collector may be an optical arrangement, a photodetector, or both. In the preferred embodiment, the electroluminescent layer stack is an organic light-emitting source.
