    摘要: A method of filtering an AC signal using a piezoelectric beam is provided. A piezoelectric film is formed on a mechanical support and a portion of the piezoelectric film forms a beam which extends beyond the mechanical support so that a cavity is formed underneath the beam, and the beam is free to vibrate in the cavity at a resonant frequency when an acoustic wave is propagated in the piezoelectric layer.A depletion region is formed under a Schottky contact which serves as a drive electrode. An unfiltered AC signal is coupled to the drive electrode thereby establishing an acoustic wave when the unfiltered AC signal comprises a component at the resonant frequency. Surface charge on the piezoelectric film resulting from vibration of the beam allows the resonant frequency component of the unfiltered AC signal to pass through the depletion region. Alternatively, the resonant frequency component can be passed by a tunnel current through the cavity.

    摘要: A heterojunction bipolar transistor (HBT) is provided having a silicon substrate in which a conventional junction base is formed. A coherently strained layer of semiconductor material having a wider band gap than silicon, such as gallium phosphide, is formed over the base to form a first portion of an emitter multilayer. A second portion of the emitter multilayer comprises silicon which can be epitaxially grown on the coherently strained layer. A thin heteropotential barrier is thus formed at the base-emitter junction which preferentially allows electrons to move from emitter to base while significantly reducing hole current from base to emitter, thereby improving emitter injection efficiency and current gain.

    摘要: A single substrate, vacuum fluorescent display including a first layer of electrically conductive material positioned on a supporting substrate and a light emitting layer including phosphor positioned on the first layer. A second layer of electrically conductive material is supported on the substrate and electrically insulated from the first layer. An electron emitting layer of low work function material is positioned on the second layer and further positioned so that emitted electrons strike the light emitting layer. Since both the electron emitting and the light emitting layers are supported on the substrate, an encapsulating window is simple and easy to construct. Integrated drivers are optionally formed in the supporting substrate.

    摘要: A vacuum gap dielectric field emission triode and a method of fabrication include a conductive layer positioned on a supporting substrate and an emitter positioned on the conductive layer. A gate metal layer electrically separated from the conductive layer defines a metal bridge gate surrounding the emitter and separated from the emitter by a substantially fixed distance. The gate metal layer defines a gate opening through the metal bridge gate overlying the emitter. An anode is positioned in spaced relationship to the gate metal layer and the triode is sealed in a substantial vacuum so that the emitter is separated from the metal bridge by the substantial vacuum and the metal bridge is separated from the anode by the substantial vacuum.
