  • Patent number: 5559399
    Abstract: An electroluminescent display includes a transparent electrode (4) and a metal assist structure (6) formed over a portion of the transparent electrode (6) such that the metal assist structure (6) is in electrical contact with the transparent electrode (4). The metal assist structure (6) includes a first refractory metal layer (10), a primary conductor layer (12) formed on the first refractory metal layer (10), and a second refractory metal layer (14) formed on the primary conductor layer (12). The first and second refractory metal layers (10, 14) are capable of protecting the primary conductor layer (12) from oxidation when the electroluminescent display is annealed to activate a phosphor layer (18). In an alternate embodiment, an electroluminescent display includes a substrate (2) and a metal electrode (22) formed on the substrate (2).

  • Patent number: 5320977
    Abstract: A novel heterostructure acoustic charge transport (HACT) device is disclosed having an optimized charge density. The device includes a transducer fabricated on a substrate structure that launches surface acoustic waves. A reflector is formed in the substrate structure at an end portion adjacent to the transducer for reflecting the surface acoustic Waves. Also included is an electrode configured with the transport channel at an end thereof distal to the transducer for generating electrical signal equivalents of the propagating electrode charge. During fabrication, the resistivity of the layers initially configured at a lower than desired value. The layer is subsequently etched to raise the resistivity to the desired value.

  • Patent number: 5159299
    Abstract: A heterostructure acoustic charge transport (HACT) device having a number of signal tap electrodes has revealed unexpected insensitivity to electrode spacing and unexpected sensitivity to electrode width. Spacing of one SAW wavelength between consecutive electrodes and an electrode width of .lambda./20 are preferred.

  • Patent number: 5128579
    Abstract: An acoustic charge transport device having a number of signal tap electrodes has revealed unexpected insensitivity to electrode spacing and unexpected sensitivity to electrode width. Spacing of one-half SAW wavelength between consecutive electrodes and an electrode width of .lambda./20 are preferred for low frequency response.

  • Patent number: 5128734
    Abstract: A simplified heterostructure charge transport device has a GaAs transport layer that is the top layer of the device, deposited on an (Al,Ga) As barrier layer for vertical confinement of charge packets. Confinement at the top surface is provided by pinning of the conduction band surface states.
