  1. 16. Design of Powder Core Motors

    Författare :Avo Reinap; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; claw-pole motor; Soft magnetic composite; Electrical engineering; 3D finite element analysis; Elektroteknik;

    Sammanfattning : The goal of the study presented in this thesis is to evaluate the advantages and drawbacks of using powder technology in the design of the iron core of small claw-pole electric motors. The use of soft magnetic composites (SMC) and compaction technology allows the creation of complex 3D iron cores. LÄS MER

    Sammanfattning : The exponential growth in wireless systems require rapid prototyping of radio frequency circuits (RF) using computer-aided design (CAD) enabled models. Most of the RF circuits (e.g. switches, amplifiers, mixers, etc. LÄS MER

  7. 20. Vertical III-V/High-k Nanowire MOS Capacitors and Transistors

    Författare :Jun Wu; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanowire; MOSFET; MOS capacitor; C-V; XPS; MOVPE; InGaAs; InAs; High-k; RF; Track-and-hold circuit;

    Sammanfattning : The emerging nanowire technology in recent years has attracted an increasing interest for high-speed, low-power electronics due to the possibility of a gate-all-around (GAA) geometry enabling aggressive gate length scaling, together with the ease in incorporating high-mobility narrow band gap III-V semiconductors such as InAs on Si substrates. These benefits make vertical nanowire transistors an attractive alternative to the planar devices. LÄS MER
