1. A Fast Pixelated Thermal-Neutron Detector
Sammanfattning : This thesis presents the study of a position-sensitive scintillation-based detector called the Solid-State Neutron Detector (SoNDe). SoNDe is being developed for cold- and thermal-neutron detection at the small-angle neutron scattering (SANS) instrument SKADI at the European Spallation Source (ESS), currently under construction in Lund, Sweden.

2. High Resolution Tip-Enhanced Raman Images of Single Molecules from First Principles Simulations
Sammanfattning : With the precise control of spatially confined plasmon (SCP), tip-enhanced Raman spectroscopy (TERS) has achieved sub-nanometer resolution, leading to the chemical and physical characterization of the single molecule by optical Raman images. In the high resolution TERS measurements, the SCP spatial distribution generates the position-dependent Raman images. LÄS MER
3. III-V Nanowire Array Solar Cells: Optical and Electrical Modelling
Sammanfattning : This thesis describes optical and electrical modelling of vertically oriented III-V semiconductor nanowire array solar cells (NWASCs).In the optical studies, three-dimensional electromagnetic modelling was carried out with the scattering matrix method and the finite element method.

4. Enhancing Direct Searches for Dark Matter : Spatial-Temporal Modeling and Explicit Likelihoods
Sammanfattning : Astronomical and cosmological observations on different scales point to the existence of dark matter. In the current cosmological paradigm this dark matter accounts for about 26% of the energy-density of the universe, yet has not been directly observed. LÄS MER
5. Neural control of standing posture
Sammanfattning : When humans are asked to stand normally, they are not completely motionless. Rather, small amounts of body movement, termed postural sway, can be observed. Although the postural sway of standing has been well described, the manner in which this sway is neurally controlled and its influence in tasks involving postural re-stabilization are not known.
