  • Patent number: 11515418
    Abstract: A tunneling transistor is implemented in silicon, using a FinFET device architecture. The tunneling FinFET has a non-planar, vertical, structure that extends out from the surface of a doped drain formed in a silicon substrate. The vertical structure includes a lightly doped fin defined by a subtractive etch process, and a heavily-doped source formed on top of the fin by epitaxial growth. The drain and channel have similar polarity, which is opposite that of the source. A gate abuts the channel region, capacitively controlling current flow through the channel from opposite sides. Source, drain, and gate terminals are all electrically accessible via front side contacts formed after completion of the device. Fabrication of the tunneling FinFET is compatible with conventional CMOS manufacturing processes, including replacement metal gate and self-aligned contact processes. Low-power operation allows the tunneling FinFET to provide a high current density compared with conventional planar devices.

  • Patent number: 11482657
    Abstract: Systems and techniques providing suitable chip structures for facilitating antenna-based thermal annealing of qubits are provided. In one example, a radio frequency emitter can comprise a voltage-controlled oscillator and an antenna. The voltage-controlled oscillator can receive power-on signals from a microcontroller, thereby causing the voltage-controlled oscillator to generate an electromagnetic wave. The antenna can then direct the electromagnetic wave onto a set of one or more capacitor pads of a Josephson junction on a superconducting qubit chip, thereby annealing the Josephson junction. In another example, a voltage regulator and a digital-to-analog converter or digital-to-digital converter can be coupled in series between the microcontroller and the voltage-controlled oscillator, thereby allowing the voltage-controlled oscillator to be voltage and/or frequency tunable and eliminating the need for external power routing as compared to photonic laser annealing.

  • Patent number: 11456392
    Abstract: Nanocomposites in accordance with many embodiments of the invention can be capable of converting electromagnetic radiation to an electric signal, such as signals in the form of current or voltage. In some embodiments, metallic nanostructures are integrated with graphene material to form a metallo-graphene nanocomposite. Graphene is a material that has been explored for broadband and ultrafast photodetection applications because of its distinct optical and electronic characteristics. However, the low optical absorption and the short carrier lifetime of graphene can limit its use in many applications. Nanocomposites in accordance with various embodiments of the invention integrates metallic nanostructures, such as (but not limited to) plasmonic nanoantennas and metallic nanoparticles, with a graphene-based material to form metallo-graphene nanostructures that can offer high responsivity, ultrafast temporal responses, and broadband operation in a variety of optoelectronic applications.
