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

    Författare :Hassan Ouacha; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; etching; Schottky contacts; noise; fluctuations; generation; mobility; noise spectroscopy; recombination; p-n diodes; carbon nanotubes; thermal reaction; junction; defects; co-sputtering; irradiation; interface states; low frequency noise;

    Sammanfattning : 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. LÄS MER

  4. 3. Magnetism in Band Gap Engineered Sputtered MgxZn(1-x)O Thin Films

    Författare :Sreekanth Mahadeva; K Venkat Rao; Lyubov Belova; Mark Fox; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Magnetron co-sputtering; MgO; MgxZn 1-x O; MnxMg 1-x O; thin films; Room-temperature ferromagnetism; band gap engineering; and intrinsic defects;

    Sammanfattning : This dissertation presents a comprehensive study of the intrinsic room temperature ferromagnetism, RTFM, in technologically important thin films of ZnO, MgO, Mg@ZnO, the so-called d0–magnets that do not contain any intrinsic magnetic elements. We also present the first report on magnetism in Mn doped MgO films fabricated by dc magnetron sputtering. LÄS MER

    Författare :Julien Zichi; Val Zwiller; Gregory Gol'tsman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superconducting nanowire sngle photon detector; SNSPD; niobium titanium nitride; NbTiN; reactive co-sputtering; quantum communications; quantum sensing; Fysik; Physics;

    Sammanfattning : The physics of single photons is fascinating, by manipulating them we can observe and probe quantum effects. Doing so requires the fabrication and utilization of single photon sources, of which many types have been developed including quantum dots, trapped atoms and ions, and color centers. LÄS MER

  7. 5. Structure and properties of Si-C-N and B-C-N thin films prepared by magnetron sputtering

    Författare :Torun Berlind; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Carbon nitride-based materials, grown by magnetron sputtering have been studied concerning microstructure and mechanical properties. Carbon nitride was alloyed with Si or B, and grown as a constituent in a layered structure. LÄS MER
