  4. 17. Current measurement by real-time counting of single charges

    Author : Jonas Bylander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; array of tunnel junctions; Coulomb blockade; radio frequency single electron transistor; SET oscillations; time correlated tunnelling; metrology; current standard; SET; charge solitons;

    Abstract : The first real-time observation of time correlated single-electron tunnelling is reported in this thesis. This is a direct detection of charge discreteness in an electrical current.When a current, I, flows through a chain of metallic islands, connected by small tunnel junctions, a lattice of charges is formed due to the Coulomb repulsion.

  5. 18. Surface Science Studies of Metal Oxides Formed by Chemical Vapour Deposition on Silicon

    Author : Patrik Karlsson; Anders Sandell; Håkan Rensmo; Marcus Bäumer; Uppsala universitet; []
    Keywords : Physics; chemical vapour deposition; high-k; metal oxides; silicon; dye-solid interface; metal organic; electron spectroscopy; scanning tunnelling microscopy; Fysik;

    Abstract : For an electronic device well-designed interfaces are critical for the performance. Studies of interfaces down to an atomic level are thus highly motivated both from a fundamental and technological point of view. READ MORE

  6. 19. Compact and Efficient Millimetre-Wave Circuits for Wideband Applications
