6. Linear and Nonlinear Transport in Quantum Nanostructures
Sammanfattning : In this thesis, electron transport in mesoscopic semiconductor nanostructures, in particular so-called electron billiards or quantum dots, is studied. The thesis can be divided into two areas: the linear response regime of transport, and the nonlinear response regime of transport. LÄS MER
7. Superconducting quantum circuits in a tunable electromagnetic environment
Sammanfattning : This thesis presents the results of an experimental study onsmall-capacitance Josephson junctions in a high impedanceenvironment. In small-capacitance Josephson junctions the charging energyEC=e2/2C becomes relevant at low temperature and thecharging effects influence the transport properties. LÄS MER
8. Molecular Alligator Clips: A Study of Metal-Molecule Contacts for Molecular Electronics
Sammanfattning : In this thesis we present a computational study of the elementary building blocks for molecular electronics, interconnected electronic devices with critical dimensions below 5 nm. Building electronic circuits on that scale requires stable connection between the various parts of the device and to the macroscopic metal electrodes, needed for power supply, support and integration with conventional electronics.

9. SiC Varactors for Dynamic Load Modulation of Microwave Power Amplifiers
Sammanfattning : The rapid consumer adoption of mobile services is leading to an exponential growth in wireless data traffic. In order to accommodate more concurrent high data-rate users, the required complexity of transmitting radio base station (RBS) power amplifiers (PAs) is increasing. LÄS MER
10. Dynamics of Vortices and Charges in Two Dimensional Arrays of Small Josephson Junctions
Sammanfattning : This thesis is based on experimental work on two dimensional (2D) Josephson junction arrays. The junctions are small (~ 0.004~0.04 µm2) so that the charging energy E~ e2/2C associated with the junction capacitance C is large. LÄS MER
