16. Coarse-Grained Models of Ionic Solutions
Sammanfattning : Room-temperature ionic liquids (RTILs) are compounds composed entirely of ions, which are liquid at temperatures below 100 degrees Celsius. Their high ionic strength and strong coupling make them useful for a number of applications, e.g. as electrolytes in supercapacitors. LÄS MER
17. Simulations of Simple Fluids and Surface Forces
Sammanfattning : A considerable part of all chemistry in nature and in industry occurs in solvents. Sol- vents affect both the interactions and the reactions of the particles immersed in them. The work in this thesis concerns the properties of ionic and polar solvents, as well as the interactions between solutes and/or dispersed particles. LÄS MER
18. Electrical Characterization of Integrated InAs Nano-Structures
Sammanfattning : This thesis analyzes the electrical properties of InAs nano-structures, that are integrated into different materials and geometries. The thesis describes integration related issues of InAs, the epitaxial synthesis of the InAs nano-structures and summarizes experimental techniques for analysis of electrical properties of the integrated structures.

19. Fast dynamics and measurements of single-charge devices
Sammanfattning : In this thesis we present measurements on several different devices, including the single-Cooper-pair box (SCB), the single-electron box, tunable superconducting resonators and so called transmon qubits.By exploiting the quantum capacitance of the SCB, its state was measured by embedding the box in a radio-frequency resonator.

20. The Single Cooper Pair Box - a Quantum-Mechanical Electronic Circuit
Sammanfattning : In this thesis the single Cooper pair box (SCB) is investigated with a radio frequency single electron transistor (RF-SET). The RF-SET is used as an electrometer to detect the charge of the SCB. The SCB can be regarded as a quantum two-level system and could therefore be a possible qubit. LÄS MER
