  1. 1. Scanning Tunnelling Microscopy and Spectroscopy of Adsorbates on Aluminium and Silicon

    University dissertation from Div. of Synchrotron Radiation Research, Department of Physics, Lund University, Box 118, S-221 00 Lund, Sweden

    Author : Mikael Johansson; Lund University.; Lunds universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alkali metals; Scanning tunnelling spectroscopies; Scanning tunnelling microscopy; Photoelectron Spectroscopy; Single crystal surface; Silicon; Surface structure; Aluminium; Silicides; Fullerenes.; Physics; Fysik; Fysicumarkivet A:1997:Johansson;

    Abstract : The main topic of this thesis is the investigation of atomic andmolecular adsorbates on single crystal surfaces of silicon and aluminiumusing the techniques of scanning tunnelling microscopy (STM) andspectroscopy (STS). The emphasis has been to use atomic-resolutionspectroscopy and imaging to determine the relationship between thesurfaces' geometric and electronic structures. READ MORE

  3. 3. Memory Illusions and Memory Attributions - Behavioural and Electrophysiological Data

    University dissertation from Department of Psychology, Lund University

    Author : Mikael Johansson; Lund University.; Lunds universitet.; [2002]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; memory illusion; false memory; misattribution; episodic memory; neurofysiologi; familiarity; recollection; source monitoring; event-related potentials; Neurology; neuropsychology; neurophysiology; neuropsykologi; Neurologi;

    Abstract : Although memory often serves us well, it can also prove highly unreliable. The study of illusions and distortions of memory unveils important information about the nature of human memory functioning and, moreover, factors affecting memory accuracy. READ MORE

  4. 4. Piecewise Linear Control Systems

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Mikael Johansson; Lund University.; Lunds universitet.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piecewise quadratic functions; Linear matrix inequalities; Convex optimization; Optimal control; Performance analysis; Piecewise linear Lyapunov functions; Piecewise quadratic Lyapunov functions; Quadratic stability; Lyapunov stability; Piecewise linear systems; Nonlinear systems; Fuzzy systems; Hybrid systems.; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : This thesis treats analysis and design of piecewise linear control systems. Piecewise linear systems capture many of the most common nonlinearities in engineering systems, and they can also be used for approximation of other nonlinear systems. READ MORE

  5. 5. Silicon device substrate and channel characteristics influenced by interface properties

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Mikael Johansson; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel; attenuation; zro2; interface; traps; semi-insulating; high-k; mos; cross-talk; hfo2;

    Abstract : This thesis is divided in two parts, one dealing with the depleted Si/Si structure, which is a substrate behaving as a semi-insulating material intended for radio-frequency applications and the other concerning high-k gate dielectrics (dielectrics with high dielectric constant) as the replacement for silicon dioxide as MOS gate dielectric.High frequency applications of CMOS integrated circuits, to lower cost, achieve higher performance and richer functionality, depends partly on the possibility to decrease the substrate coupling between different parts of the circuit.
