  2. Resonant-tunneling diode - Wikipedia

    en.wikipedia.org/wiki/Resonant-tunneling_diode

    A resonant-tunneling diode (RTD) is a diode with a resonant-tunneling structure in which electrons can tunnel through some resonant states at certain energy levels. The current–voltage characteristic often exhibits negative differential resistance regions.

  3. Tunnel diode - Wikipedia

    en.wikipedia.org/wiki/Tunnel_diode

    The resonant-tunneling diode (RTD) has achieved some of the highest frequencies of any solid-state oscillator. [10] Another type of tunnel diode is a metal-insulator-insulator-metal (MIIM) diode, where an additional insulator layer allows "step tunneling" for more precise control of the diode. [11]

  4. Quantum tunnelling - Wikipedia

    en.wikipedia.org/wiki/Quantum_tunnelling

    The resonant tunnelling diode makes use of quantum tunnelling in a very different manner to achieve a similar result. This diode has a resonant voltage for which a current favors a particular voltage, achieved by placing two thin layers with a high energy conductance band near each other.

  5. Negative resistance - Wikipedia

    en.wikipedia.org/wiki/Negative_resistance

    The tunnel diode circuit (see diagram) is an example. [82] The tunnel diode TD has voltage controlled negative differential resistance. [54] The battery adds a constant voltage (bias) across the diode so it operates in its negative resistance range, and provides power to amplify the signal.

    Unlike classical diodes, its current is carried by resonant tunneling through two or more potential barriers (see figure at right). Its negative resistance behavior can only be understood with quantum mechanics: As the confined state moves close to Fermi level, tunnel current increases. As it moves away, the current decreases.

    en.wikipedia.org/wiki/Types_of_physical...

    It has been shown that quantum confinement effects can be used to construct a PUF, in devices known as resonant-tunneling diodes. These devices can be produced in standard semiconductor fabrication processes, facilitating mass-production of many devices in parallel. This type of PUF requires atom-level engineering to clone and is the smallest ...
