  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. ECG –measurements

    University essay from

    Author : Elnaz Ekramian; Nergis Lali Watanwall; [2017]
    Keywords : ;

    Abstract : Context: In this project we aimed to investigate the ECG-measurement which is used to monitoring the heart activity in order to discover heart problems based on the beats and rhythms. Therefore this old technology is very popular at clinics. READ MORE

  4. 4. Design, fabrication and measurements of planar Goubau lines from 0.75 THz to 1.1 THz

    University essay from Chalmers tekniska högskola/Institutionen för mikroteknologi och nanovetenskap

    Author : Juan Cabello Sanchez; [2017]
    Keywords : Terahertz; WR1; Planar Goubau lines; mode launchers; on-wafer probe measurements; BCB; biosensors; lab-on-a-chip; impedance transformers.;

    Abstract : Terahertz (THz) waves have proven to possess a unique interaction with biomolecules, and therefore it’s interesting to study its influence using biosensors. Recent advances in heterodyne technology allow measuring on-wafer scattering parameters with Vector Network Analysers (VNA) up to 1.1 THz, which could be used for THz molecular spectroscopy.

  5. 5. An Investigation on PVDF Piezoelectric Elements and Linear Array Transducers

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Ali Alkhudri; [2017]
    Keywords : Ultrasonic Transducer; Piezoelectric Element; PVDF; Frequency; Ultrasound Wave Penetration; PZT; Acoustic Impedance; raw data; linear array transducer; Technology and Engineering;

    Abstract : Ultrasonic waves are widely used in different application e.g. for sonar scanning in water and fetal imaging. Furthermore it is used for doing measurements on different materials to determine the thickness of the material or the velocity of sound inside it. READ MORE
