  4. 2. Characterisation of the Specific Capacitance of Superconducting Tunnel Junctions

    Author : Parisa Yadranjee Aghdam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Superconductor-Insulator-Superconductor tunnel junctions; Microwave measurement; Capacitance; Calibration;

    Abstract : Superconductor-Insulator-Superconductor (SIS) tunnel junctions are widely used as the mixing component in mm and sub-mm receivers for radio astronomy and environmental science. SIS mixers offer superior noise performance close to the quantum limit for frequencies up to 1 THz. READ MORE

  5. 3. Novel Processing and Electrical Characterization of Nanowires

    Author : Kristian Storm; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gate; Capacitance; Hall effect; InP; InAs; Characterization; Nanowires; Processing; LED; Transistor; Fysicumarkivet A:2013:Storm;

    Abstract : This thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. READ MORE

  6. 4. Affinity biosensors based on a capacitive transducer

    Author : Christine Berggren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembled monolayers; capacitance; heavy metal ion; non-labeled; nucleic acid; DNA biosensor; Biosensor; immunosensor; Analytical chemistry; Analytisk kemi;

    Abstract : Capacitive biosensors were developed for several analytes such as hormones, interleukines, viruses and heavy metal ions. The sensing surfaces were prepared by immobilizing the biorecognition element to self-assembled monolayers (SAMs) on gold. SAMs form spontaneously on gold by adsorption of thiols, sulfides or disulfides. READ MORE

  7. 5. Protein-based capacitive biosensors for the detection of heavy-metal ions

    Author : Alessia Mortari; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy metal ions; protein; electrode; Biosensor; capacitance;

    Abstract : Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. READ MORE
