    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; condensed matter; electrics; electrical; materials science; Elektroteknik; elektronik och fotonik; TECHNOLOGY Electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik;

    Sammanfattning : The continuing shrinkage of semiconductor devices towards nanoscale features and increased functionality has prompted a strong need for high-resolution characterization tools capable of mapping the electrical properties with nanoscale lateral resolution. In this regard, scanning capacitance microscopy (SCM) scanning spreading resistance microscopy (SSRM) and Kelvin probe force microscopy (KPFM) have emerged as powerful techniques. LÄS MER

    Sammanfattning : The use of CMOS technologies for microwave and millimeter wave applications has recently been made possible as a result of increased transistor performance. The fT and fmax have, for example, passed 100 GHz at the 130 nm node and 200 GHz at the 65 nm node. LÄS MER

  3. 3. Upconversion in Er doped silica : - characterization and modeling

    Detta är en avhandling från Kista : Mikroelektronik och informationsteknik

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; elektronik och fotonik; TECHNOLOGY Electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik;

    Sammanfattning : Further increase of erbium concentrations in Er-doped amplifiers and lasers is needed for the design of efficient, reliable, compact and cost-effective components for telecommunications and other photonic applications. However, this is hindered by Er concentration dependent loss mechanism known as upconversion. LÄS MER

  4. 4. Aging and Characterization of Semiconducting Glazes

    Detta är en avhandling från Chalmers University of Technology

    Författare :Heike Ullrich; Chalmers tekniska högskola.; Chalmers University of Technology.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics;

    Sammanfattning : Semiconducting glazes on ceramic insulators had been introduced as a solution for improving the performance of high voltage insulators especially under heavily polluted conditions. The major concern in using such glazes, despite their approved advantages, is the observed aging of the surface with exposure time, leading to reduction of conductivity and deterioration of the glaze itself, especially under dc voltage.
