  1. 1. Passivation of Gallium Arsenide Nanowires for Solar Cells

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

    Author : Austin Irish; [2019]
    Keywords : nanowires; semiconductors; solar cells; photovoltaics; passivation; electronics; chemistry; polymers; hydrazine; plasma; gallium; arsenic; iii-v; epitaxy; photoluminescence; time-resolved; spectroscopy; Physics and Astronomy;

    Abstract : A strategic and diverse set of passivation methods for gallium arsenide nanowires wasstudied. Using a time-resolved photoluminescence setup at100 Kand300 K, the radiativerecombination of charge carriers was resolved on a picosecond time scale. READ MORE

  3. 2. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Vidar Flodgren; [2019]
    Keywords : GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

    Abstract : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. READ MORE

  4. 3. Development of an Automated Test Platform for Characterization and Performance Assessment of Electronic Modules in Electric Thrusters : The TESPEMET Project

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sri Harsha Pavuluri; [2019]
    Keywords : rf ion thruster; electric thruster; automated test; micropython; test platform;

    Abstract : There has been a sharp increase in the market for electric propulsion systems for small satellites in the recent years. Electric propulsion systems have become smaller, more efficient and cheaper, which made them ideal for small satellites because they have a low thrust requirement and benefit significantly from the high specific impulse (Isp) that is characteristic to electric thrusters.

  5. 4. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Pablo Martinez Cano; [2019]
    Keywords : LISA; PCB; temperature; passive; aluminum; aluminium;

    Abstract : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.

  6. 5. Development of a Mobile Reactor for Large Scale Water Treatment

    University essay from Umeå universitet/Institutionen för fysik

    Author : Alexander Berggren; [2019]
    Keywords : Water treatment; Mobile reactor; Autopilot; Rotating Bed Reactor;

    Abstract : Water pollution is one of many environmental problems that currently exists and inadequate treatment of industrial wastewater is contributing to further pollution. SpinChem AB's Rotating Bed Reactor (RBR) technology offers the possibility of water treatment by carrying out reactions between a solution and a solid phase. READ MORE
