  1. 1. Low-Frequency Noise in InGaAs Nanowire MOSFETs

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

    Author : Christian Mario Möhle; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Low-frequency (LF) noise (1/f as well as random telegraph-signal (RTS) noise) measurements were performed on high-performance InGaAs nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs). 1/f noise measurements at room temperature (RT) show that the dominant noise mechanism is carrier number fluctuations.

  2. 2. The status of neutron-capture elements according to Gaia-ESO.

    University essay from Lunds universitet/Astronomi

    Author : Linnéa Strandell; [2017]
    Keywords : Neutron-capture elements; Gaia-ESO; Milky Way field stars; Physics and Astronomy;

    Abstract : The aim of this thesis is to get a better understanding of the evolution of the Milky Way stellar disc by looking at the abundance ratios for neutron-capture elements in thin and thick disc stars. In this project the formation of our Galaxy’s thin and thick disc was studied by analysing 10 different neutron-capture elements in field stars measured by Gaia-ESO. READ MORE

  3. 3. Non-destructive testing of thin strip material : Implementation of the 3MA technique at a steel producing company

    University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Author : Jon Mikel Lizarralde; [2017]
    Keywords : Non-destructive testing; 3MA; steel strip; process monitoring and control; energy efficiency; sustainability; hardness; tensile strength;

    Abstract : This study is an initial attempt to investigate the possibility of substituting conventional laboratory destructive testing techniques at Sandvik's strip steel production facilities with the 3MA (Micro-magnetic Multi-parameter Microstructure and Stress Analysis) NDT (nondestructive testing) technique. The interest for the research comes from various problems with the actual destructive testing method. READ MORE

  4. 4. Wireless system design : NB-IoT downlink simulator

    University essay from Uppsala universitet/Signaler och System; Uppsala universitet/Signaler och System

    Author : Piotr Krasowski; Douglas Troha; [2017]
    Keywords : nb-iot; lte; lte-a; downlink; simulator; wireless;

    Abstract : The newly defined NB-IoT standard currently lacks a toolkit and simulator. In order to develop algorithms for this new standard there is a need for channels and signals as reference during tests. MATLAB is commonly used for testing LTE signals and therefore the toolkit was developed in this environment. READ MORE

  5. 5. Hyperfine structure measurements in scandium for IR spectroscopy

    University essay from Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Felix van Deelen; [2017]
    Keywords : Astrophysics; Atomic Data; Hyperfine Structure; Stellar Spectroscopy; Physics and Astronomy;

    Abstract : Stellar abundances are important for understanding the chemical evolution of galaxies and provide us with constraints on stellar evolution and supernova nucleosynthesis. To determine stellar abundances accurately, atomic data is crucial. This data is incomplete for many elements, especially in the infrared region. READ MORE
