  2. 1. Electrical Characterization of Metal-Oxide-Silicon Structures with Ultra Thin Oxide Layers

    Author : Per Lundgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tunneling; MTOS; oxide defects; MOS; PMA;

    Abstract : Metal-oxide-semiconductor (MOS) structures with very thin (2 - 4 nm) oxide layers thermally grown on silicon have been electrically characterized regarding oxide and interface defects and concerning the direct tunnel current through the oxide. This thesis comprises eight papers which deal with the appearance of oxide charge during electrical stress (papers A, D, E), the beneficial effect on the defect density of low-temperature (up to 350 °C) post-metallization annealing (PMA) (paper A, B, C, G), and the effect of temperature and choice of metal for the tunnel current (paper F, H).

  6. 4. Prostate cancer : population-based screening and markers for long-term clinical outcome

    Author : Per-Olof Lundgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In 1988 and 1989 a large screening study for prostate cancer was launched in Stockholm, Sweden. At the time approximately 27 000 men between 55 and 70 years of age resided within a defined area of southern Stockholm. READ MORE

  7. 5. Implementation and real-world evaluation of routing protocols for wireless ad hoc networks

    Author : Henrik Lundgren; Per Gunningberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Abstract : A wireless ad hoc network consists of a number of mobile nodes that temporarily form a dynamic infrastructure-less network. To enable communication between nodes that do not have direct radio contact, each node must function as a wireless router and potentially forward data traffic on behalf of the others. READ MORE
