  1. 1. Noise Aspects of some Si-based One Port Devices and Carbon Nanotubes

    University dissertation from Chalmers University of Technology

    Author : Hassan Ouacha; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; noise; low frequency noise; Schottky contacts; p-n diodes; junction; defects; noise spectroscopy; fluctuations; mobility; recombination; generation; interface states; irradiation; etching; co-sputtering; thermal reaction; carbon nanotubes;

    Abstract : The p-n junctions and Schottky diodes based on Si1-xGex and SiC are of great importance in modern electronic applications, such as microwave detectors and mixers. Carbon nanotubes (CNTs) have appeared recently as an attractive new class of materials with a reduced dimensionality, and proposed as building blocks for nanoelectronic technology. READ MORE

  3. 3. Simulation and Electrical Evaluation of 4H-SiC Junction Field Effect Transistors and Junction Barrier Schottky Diodes with Buried Grids

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jang-Kwon Lim; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide SiC ; junction field-effect transistors JFETs ; junction barrier schottky diode JBS ; schottky barrier diode SBD ; buried-grid BG technology; simulation; implantation; epitaxial growth; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Silicon carbide (SiC) has higher breakdown field strength than silicon (Si), which enables thinner and more highly doped drift layers compared to Si. Consequently, the power losses can be reduced compared to Si-based power conversion systems. Moreover, SiC allows the power conversion systems to operate at high temperatures up to 250 oC. READ MORE

  4. 4. Growth of Semiconductor Nanowires for Solar Cell Applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Magnus Heurlin; Lunds universitet.; Lund University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MOVPE; Aerotaxy; III-V semiconductor materials; nanowire; solar cells; photovoltaics; Fysicumarkivet A:2015:Heurlin;

    Abstract : Nanowires have the ability to absorb light much more efficient than conventional thin film layers. This makes them candidates for the development of new types of solar cells that have higher efficiency and lower material usage than current technologies. READ MORE

  5. 5. Polymer light-emitting electrochemical cells Utilizing doping for generation of light

    University dissertation from Umeå : Department of Physics, Umeå University

    Author : Piotr Matyba; Umeå universitet.; [2011]
    Keywords : ;

    Abstract :     The current implementation of conjugated polymers (“conducting plastics”) in a wide range of devices promises to bring the vision of a new generation of flexible, efficient and low-cost applications to reality. Plastic lightemitting devices in the form of polymer light-emitting diodes (PLEDs) are projected to be particularly close to the market in applications such as large area and conformable illumination panels and high-performance thin displays.
