  • QUANTUM TUNNELING DEVICES FOR GENERATION OF HARMONICS IN PASSIVE WIRELESS TAGS AND SENSORS
    Publication number: 20230035139
    Abstract: A tag detection system comprising a source for producing an interrogation signal having a first frequency; a harmonic radar tag comprising: an antenna structure; a tunneling junction electrically and integrally coupled to the antenna; and wherein the harmonic radar tag when stimulated by the interrogation signal having the first frequency, and the harmonic radar tag produces a response signal at a second frequency different from the first frequency.

  • Clipped amplifier
    Patent number: 10164595
    Abstract: A clipping circuit for an amplifier, the clipping circuit using a tunneling junction. A molecular or other tunneling electronic-based component within a hybrid analog-tunneling circuit is used to produce soft or hard clipping capability with enhanced control over the output. The circuit may be used as a distortion circuit for an electric guitar signal or other electronic signals.

  • Two- and three-terminal molecular electronic devices with ballistic electron transport
    Patent number: 9024297
    Abstract: Two- and three-terminal molecular electronic devices with ballistic electron transport are described. For example, a two-terminal molecular electronic device includes a conductor 1 layer/molecule 1 layer/conductor2 layer junction, wherein the total thickness of the molecule 1 layer and the conductor2 layer is less than or approximately equal to the mean free path of a charge carrier traveling in the two layers, and wherein ballistic transport can occur for some fraction of a plurality of charge carriers in the two layers.
