  1. 1. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Yoana Ilarionova; [2023]
    Keywords : Physics and Astronomy;

    Abstract : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. READ MORE

  3. 2. Automated High-Temperature Pressure Sensor Verification and Characterization

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Algirdas Bartkevicius; [2023]
    Keywords : Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

    Abstract : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. READ MORE

  4. 3. Definition and evaluation of a system for measuring local geomagnetic variations : Autonomous station for magnetic measurements

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Viktor Olsson; [2023]
    Keywords : Local Geomagnetic Variations; Fluxgate Magnetometer; Space Weather; Solar Wind; Magnetic Measurements; Variometer; Solar Activity.; Lokala geomagnetiska variationer; Fluxgate-Magnetometer; Rymdväder; Solvinden; Magnetiska Mätningar; Variometer; Solaktivitet.;

    Abstract : Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology. These events are summarized under the concept of space weather. This creates variations in Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. READ MORE

  5. 4. Can iba detect the next compressor failure? : Condition-based monitoring applied to nitrogen compressor – a case study

    University essay from Högskolan i Gävle/Elektronik

    Author : Kalle Kurttio; [2023]
    Keywords : predictive maintenance; condition-based monitoring; screw compressor; reciprocating compressor; ibaAnalyzer; ibaHD-server;

    Abstract : Production of steel powder is done by atomization of a molten steel stream. Atomization is done by feeding high pressure nitrogen gas through nozzles, creating jets of gas which scatter the molten steel stream into powder. The steel powder falls through the atomization tower whilst it cools and solidifies. READ MORE

  6. 5. Simulation of Quantum Cascade Lasers

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Zakaria Mohamed; [2023]
    Keywords : Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

    Abstract : 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
