1. Silicon nanowire based devices for More than Moore Applications
Sammanfattning : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. LÄS MER
2. Engineering Epitaxial Graphene for Quantum Metrology
Sammanfattning : Quantum resistance metrology deals both with the precise and accurate measurement of electrical resistance, by utilizing the quantum hall effect (QHE) in two-dimensional electron gases (2DEGs) such as those based on gallium arsenide (GaAs). Due to the unique properties of graphene, and specifically epitaxial graphene grown on silicon carbide (SiC/G), quantum Hall resistance (QHR) standards based on graphene perform better in a wider parameter space (temperature, current and magnetic field) than conventional semiconducting materials.

3. Fabrication of Integrated HBV Multipliers for THz Generation
Sammanfattning : The main objective of this licentiate thesis is to demonstrate silicon integrated HBV frequency multipliers for THz generation with RF performance comparable with InP technology. The choice of silicon is motivatedby better thermal and mechanical properties, cost and ease of integration compared to III-V semiconductor substrates. LÄS MER
4. Silicon Integrated HBV Frequency Multipliers for THz Applications
Sammanfattning : This thesis deals with integrated varactor diode circuits for terahertz (THz) applications. In particular hybrid, monolithic microwave integrated circuits (MMICs), and heterogeneous integration are explored for frequency multiplier applications. LÄS MER
5. Stochastic Resonance and Noise-Assisted Signal Transfer : On Coupling Effects of Stochastic Resonators and Spectral Optimization of Fluctuations in Random Network Switches
Sammanfattning : Recent research shows that noise or random fluctuations must not always be destructive in Nature by degrading system performance. On the contrary, in nonlinear systems they can synchronize systems or enhance the quality of signal transmission. The latter possibility is reported in the thesis. LÄS MER
