1. Ion Tracks for Micro- and Nanofabrication : From Single Channels to Superhydrophobic Surfaces
Sammanfattning : A method is described for preset-count irradiations between 1 and 100 ions singling-out individual ions from an ion beam with more than a billion ions arriving per second. The ion tracks are etched in a conductometric system with real-time evaluation of the acquired data. The etch process can be interrupted when reaching a preset channel diameter. LÄS MER
2. Synthesis of Thin Piezoelectric AlN Films in View of Sensors and Telecom Applications
Sammanfattning : The requirements of the consumer market on high frequency devices have been more and more demanding over the last decades. Thus, a continuing enhancement of the devices’ performance is required in order to meet these demands. In a macro view, changing the design of the device can result in an improvement of its performance. LÄS MER
3. Advanced MEMS Pressure Sensors Operating in Fluids
Sammanfattning : Today’s MEMS technology allows manufacturing of miniaturized, low power sensors that sometimes exceeds the performance of conventional sensors. The pressure sensor market today is dominated by MEMS pressure sensors.In this thesis two different pressure sensor techniques are studied. LÄS MER
4. Reef biostromes and related facies from the Middle Silurian of Gotland, Sweden
Sammanfattning : Reef biostromes and related facies from the upper part of Wenlock and from Ludlow were investigated in order to account for their formation, their palaeoecology and biology. In the Hemse Group of Ludlow age, all studied biostromes comprise a low diversity fauna where one or few species dominates. LÄS MER
5. Epitaxy of oxide and nitride thin films grown by magnetron sputtering
Sammanfattning : The need for electronic devices with new functionalities has caused research to move in a way to design and utilize materials with high-performance thermoelectricity, widely used in batteries, sensors, and electronic devices. Two-dimensional materials (2D) with unique structures and remarkable properties have been identified to fabricate oxide heteroepitaxy. LÄS MER
