1. Implementation of Dyson equation to accelerate convergence in RS-LMTO-ASA code
Master-uppsats, Uppsala universitet/MaterialteoriSammanfattning : First-principle calculations is a key ingredient for us to understand, improve and design new materials. Density functional theory (DFT) [1] has proven to be a very powerful tool and a number of different versions exist depending on the problem at hand. LÄS MER
2. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment
Master-uppsats, Linköpings universitet/InformationskodningSammanfattning : This master’s thesis explores a space-division-multiplexing (SDM) platform fora delayed-choice experiment. SDM is a multiplexing technique for optical datatransmission that employs spatial modes in a multi- or few-mode fiber to increasethe transmission capacity. The spatial modes can thus be used as separate channels. LÄS MER
3. Localized and extended states in finite-sized mosaic Wannier-Stark lattices
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

4. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. LÄS MER
5. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. LÄS MER
