  2. 1. Probing nonlinear electrical properties at the nanoscale : Studies in multifrequency AFM

    Author : Riccardo Borgani; David B. Haviland; Peter Grütter; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atomic Force Microscopy; Nonlinear dynamics; Multifrequency; Contact potential difference; Conductance; Fast dynamics; Fysik; Physics;

    Abstract : Nanostructured materials promise great advances in diverse and active research fields such as energy harvesting and storage, corrosion prevention and high-density memories. Electrical characterization at the nanometer scale is key to understanding and optimizing the performance of these materials, and therefore central to the progress of nanotechnology. READ MORE

  4. 2. Quantum effects in nanoscale Josephson junction circuits

    Author : Silvia Corlevi; David B. Haviland; Jukka Pekola; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; Josephson junction arrays; electromagnetic environment; Cooper pair transistor; parity effects; Physics; Fysik;

    Abstract : This thesis presents the results of an experimental study on single-charge effects in nanoscale Josephson junctions and Cooper pair transistors (CPTs). In nanoscale Josephson junctions the charging energy EC becomes significant at sub-Kelvin temperatures and single-charge effects, such as the Coulomb blockade of Cooper pair tunneling, influence the transport properties.

  5. 3. Fabrication and Characterization of Superconductive Coplanar Waveguide Resonators : Fabrication and Characterization of Superconductive Coplanar Waveguide Resonators

    Author : Adem Ergül; David B. Haviland; Vladimir Krasnov; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coplanar; Waveguide; Resonator; Superconductive; Fabrication; Characterization; Superconductivity; Supraledning;

    Abstract : The objective of this thesis is to evaluate a generic process for fabrication and characterization of the Superconductive coplanar waveguide (CPW) resonators. Superconductive CPW resonators with various lengths and shapes are designed to investigate their electrical and magnetic properties as well as resonance properties and sensitivities. READ MORE

  6. 4. Nonlinear dynamics of Josephson Junction Chains and Superconducting Resonators

    Author : Adem Ergül; David B. Haviland; Per Delsing; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Josephson Junction; SQUID; Superconducting Resonators;

    Abstract : This thesis presents the results of the experimental studies on two kindof Superconducting circuits: one-dimensional Josephson junction chains andsuperconducting coplanar waveguide (CPW) resonators. One-dimensionalJosephson junction chains are constructed by connecting many Superconducting quantum interference devices (SQUIDs) in series. READ MORE

  7. 5. Imaging materials with intermodulation : Studies in multifrequency atomic force microscopy

    Author : Daniel Forchheimer; David Haviland; Arvind Raman; KTH; []
