  2. 6. Studies on performance limitations in CMOS DACs

    Author : K. Ola Andersson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The digital-to-analog converter (DAC) is a bottle neck in broadband communication systems. High update rates are required in combination with high accuracy. READ MORE

  4. 7. Correlation Effects in Nanostructures

    Author : Paata Kakashvili; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conformal field theory; Coulomb blockade; Wigner crystal.; Strongly correlated electrons; Kondo effect; bosonization; Luttinger liquid; STM; single-electron transistor;

    Abstract : In this Ph.D. thesis I present the background and providefurther details to the work presented in the appended papers. The background consists of brief overviews of Kondo physics, Luttinger liquid theory, and conformal field theory. READ MORE

  5. 8. Cation intercalation and surface fractality in metal oxide based films

    Author : Maria Strømme Mattsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : New methods have been developed for determining the fractal dimension df of asurface from cyclic voltammograms with the sample of interest serving as the workingelectrode in an electrochemical cell. The methods have been verified by applying them tovoltammograms recorded on gold samples with a well-defined fractal dimension. READ MORE

  6. 9. Vertical III-V Semiconductor Devices

    Author : Tomas Bryllert; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Halvledarfysik; Semiconductory physics; heterostructure barrier varactor frequency multiplier; field effect transistor; resonant tunneling; artificial molecule; terahertz; nanowire; Quantum dots;

    Abstract : This thesis is based on three projects that deal with vertical III-V semiconductor devices. The work spans over basic research as well as more applied aspects of III-V semiconductor technology. All projects have in common that they rely on advanced epitaxial growth to form the starting material for device fabrication. READ MORE

  7. 10. Analysis of dielectric response measurement methods and dielectric properties of resin-rich insulation during processing

    Author : Anders Helgeson; KTH; []
    Keywords : ;

    Abstract : The dielectric diagnostic methods ofpolarisation/depolarisation currents and recovery voltage,which are time domain methods, and capacitance and tandmeasurements at different frequencies, which is a frequencydomain method, have been studied here. In the first part of thethesis, these measurement methods are analysed and evaluated. READ MORE
