11. Experimental Studies of Charge Transport in Single Crystal Diamond Devices
Sammanfattning : Diamond is a promising material for high-power, high-frequency and high- temperature electronics applications, where its outstanding physical properties can be fully exploited. It exhibits an extremely high bandgap, very high carrier mobilities, high breakdown field strength, and the highest thermal conductivity of any wide bandgap material. LÄS MER
12. Monte Carlo Simulations of Homogeneous and Inhomogeneous Transport in Silicon Carbide
Sammanfattning : The importance of simulation is increasing in the researchon semiconductor devices and materials. Simulations are used toexplore the characteristics of novel devices as well asproperties of the semiconductor materials that are underinvestigation, i.e. generally materials where the knowledge isinsufficient.

13. Electrical Transport in Nanoparticle Thin Films of Gold and Indium Tin Oxide
Sammanfattning : Electrical transport properties of nanoparticle gold films made by the gas evaporation method were analysed using resistivity measurements. Low temperature electrical transport measurements showed a cross-over from a temperature range dominated by inelastic scattering to a temperature range dominated by elastic scattering, presumably by grain boundaries.

14. Predictive Simulations of Transport in Tokamak
Sammanfattning : The understanding of anomalous transport mechanisms in magnetically confined plasmas is one of the most central issues for the achievement of controlled thermonuclear fusion. Even though this problem has been given a very high priority since the very beginning of the magnetic fusion research programs, there are several outstanding issues that remain to be resolved.

15. On transport theory of correlated mesoscopic systems
Sammanfattning : This thesis is about the theory of quantum transport through low dimensional correlated systems. Correlated systems are interacting many-particle systems where collective effects predominate over the individual properties of particles whereof they consist. Single particle approach to correlated systems would be essentially wrong. LÄS MER
