1. Chloride Homeostasis in Central Neurons
Sammanfattning : The overall aim of the present thesis is to clarify the control of intracellular chloride homeostasis in central neurons, because of the critical role of chloride ions (Cl–) for neuronal function. Normal function of the central nervous system (CNS) depends on a delicate balance between neuronal excitation and inhibition. LÄS MER
2. Charge carrier traffic at interfaces in nanoeletronic structures
Sammanfattning : This thesis describes investigations in relation to the search for materials with high dielectric constant, k, for future CMOS transistors. The most elementary quantities to be considered are k-value and energy band offsets between the dielectric and the silicon crystal on which it is deposited. LÄS MER
3. Electromechanical Interactions in Shuttle Systems and Carbon Nanotube Relays
Sammanfattning : In this thesis we theoretically investigate two kinds of nanoscale systems where there is a strong electromechanical coupling, i.e. an intricate relation between the Coulomb forces that can appear in these systems and the displacements of parts of the systems that they cause.

4. Nonlinear dynamics of Josephson Junction Chains and Superconducting Resonators
Sammanfattning : This thesis presents the results of the experimental studies on two kindof Superconducting circuits: one-dimensional Josephson junction chains andsuperconducting coplanar waveguide (CPW) resonators. One-dimensionalJosephson junction chains are constructed by connecting many Superconducting quantum interference devices (SQUIDs) in series. LÄS MER
5. Exploring two facets of physics: Coherent current transport in superconducting structures. Phenomenographic studies of sense-making in physics
Sammanfattning : This thesis has two major parts. It draws upon and contributes both to the physics and the pedagogical research traditions. It consists of two acts, and a discussion on the relation between the two acts. The main result in the physics part is the development of a coherent MAR (multiple Andreev reflection) theory for SNS junctions. LÄS MER
