11. Design and fabrication of Si diaphragms for capacitive pressure sensors in high-pressure microfluidics
University essay from Uppsala universitet/MikrosystemteknikAbstract : The pressure has a major impact when it comes to control of chemical processes. A method for integrating electrical pressure sensors in high-pressure microfluidic chips has, however, so far not been developed and the aim of this project was therefore to study how capacitive pressure sensors could be designed and fabricated to measure pressures between 1-100 bar.

12. AlP sacrificial layer for GaP NW growth
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : III-V semiconductor nanowires (NWs) display outstanding potential for many technological applications, but their implementation into devices is restricted due to high material and fabrication costs. Common techniques for NW synthesis rely on single crystalline substrates, which are single-use and have large costs associated to them. READ MORE

13. Extraction Replicas of Common Engineering Alloys for Analysis of Small Precipitates
University essay from KTH/MaterialvetenskapAbstract : Characterization of small precipitates is important for development of new alloys. One inherent difficulty in characterisation of small precipitates with electron microscopy techniques while the particles are embedded in the matrix, is that the surrounding bulk material will contribute to the analysed signal- limiting, for example, the quantification of the composition of particles.

14. Fabrication and characterization of novel nano-magnets
University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysikAbstract : Magnetic data storing has been of great interest since 1950 when the first magnetic hard drive was fabricated. A lot has happened since then, but there is still a need for smaller and cheaper devices. One way to achieve this is by creating nano-sized ferromagnetic areas in a thin film at room temperature, or nano-magnets. READ MORE

15. Patterning of perovskite thin films for electrical and optical characterisation
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : While perovskite solar cells have become increasingly more efficient and popular, electrical characterisation of the semiconductor properties of perovskites has been limited due to the instability of the material. In this work, multiple approaches for creating such electrical test structures from perovskites are discussed. READ MORE
