1. Simulation of Quantum Cascade Lasers
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikAbstract : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. READ MORE

2. In-situ Growth of Sn-seeded GaAs and GaSb Nanowire Heterostructures
University essay from Lunds universitet/Centrum för analys och syntesAbstract : One of the ways to utilize III-V nanowires, is to make use of the possibility to combine materials and create heterostructures which allows for creating material combinations with new properties. A special interest can be taken into Sb-containing nanowires due to the high electron mobility, however there has been reported difficulties with switching to other materials because of a 'memory effect' where Sb lingers in the system and nanowire.

3. Thermoelectric measurements on InAs nanowires with a ratchet-barrier
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysikAbstract : Efficient extraction of thermal energy from electrons at the micro- and nanoscale is a long-standing scientific goal that could enable novel types of heat engines, heat management, and solar cell applications. Semiconductor nanowires are a promising system for investigating such devices for several reasons, such as their thermoelectric properties, and the potential to be grown in heterostructures with high flexibility.

4. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts
University essay from Lunds universitet/Kemiska institutionenAbstract : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. READ MORE

5. Demonstration and investigation of hydrogen production by water splitting through plasmon assisted photocatalysis involving a cobalt catalyst.
University essay from Uppsala universitet/Fysikalisk kemiAbstract : Plasmonic heterostructures are of great interest within the industry and in the academia owing to theirapplications in photovoltaics and photocatalysis. The Localised surface plasmon resonance (LSPR) leading to an intensification of the electromagnetic (EM) field on the surface of the plasmonic nanoparticles results in an efficient absorption of light over miniscule thickness of the material.
