  1. 1. Electrical Characterization of Silicon Nanogaps

    Författare :Jonas Berg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic molecules; Molecular electronics; Surface leakage currents; Low-frequency noise; Soft breakdown; TSRAM; Resonant tunneling diodes; Selective etching; Silicon nanogaps; Nanocontacts;

    Sammanfattning : We have designed and manufactured silicon nanogaps aimed at electrically interfacing molecules, utilizing the precision thickness control in an oxidation process. An insulating layer was formed on a silicon wafer, and then polysilicon was deposited on top. LÄS MER

  3. 2. Nanomechanics – Quantum Size Effects, Contacts, and Triboelectricity

    Författare :Martin Olsen; Jonas Örtegren; Håkan Olin; Per Gradin; Peter Glans; Rusen Yang; Mittuniversitetet; []
    Nyckelord :triboelectricity; adatom; ion; charge; mound; quantum size effect; triboelctric nanogenerator; TENG; wind driven; contact; nanomechanics; fri electron model; nanowire cantilever;

    Sammanfattning : Nanomechanics is different from the mechanics that we experience in everyday life. At the nano-scale, typically defined as 1 to 100 nanometers, some phenomena are of crucial importance, while the same phenomena can be completely neglected on a larger scale. LÄS MER

  4. 3. Spin transfer torques and spin dynamics in point contacts and spin-flop tunnel junctions

    Författare :Alexander Konovalenko; Vladislav Korenivski; David W. Abraham; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spin dynamics; spin transfer torques; point contacts; magnetization dynamics; Physics; Fysik;

    Sammanfattning : The first part of this thesis is an experimental study of the spin-dependent transport in magnetic point contacts. Nano-contacts are produced micromechanically, by bringing a sharpened non-magnetic (N) tip into contact with a ferromagnetic (F) film. LÄS MER
