  1. 21. Mechanical properties of SiC nanowires with polytypes

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Anders Vesti; [2019]
    Nyckelord :atomistic modeling; nanowires; molecular dynamics; simulation; SiC; silicon carbide; fracture behavior; nanomechanics; Physics and Astronomy;

    Sammanfattning : In this report, we model the mechanical properties and fracture behavior of SiC nanowires with different polytypes using Molecular Dynamics (MD) simulations. The mechanical properties investigated are the Young’s modulus, the maximum tensile stress and the fracture strain. The three polytype tested are SiC (3C), (2H) and (4H). LÄS MER

  3. 22. Optical studies of wrapgated InP nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Henrik Torstensson; [2019]
    Nyckelord :Nanowire; InP; ITO; wrapgate; photoluminescence; interface states.; Physics and Astronomy;

    Sammanfattning : This thesis describes optical spectroscopy on III-V semiconductor InP nanowires (NW) with a transparent indium-tin-oxide (ITO) gate electrode. The NWs are arranged both as vertical arrays with a wrap all around gate and as single lateral NWs with an omega-shaped gate for increased electrostatic effect. LÄS MER

  4. 23. Simulation of Mobile Robots with Unity and ROS : A Case-Study and a Comparison with Gazebo

    Master-uppsats, Högskolan Väst/Avdelningen för produktionssystem (PS)

    Författare :Anna Konrad; [2019]
    Nyckelord :Simulation; mobile robots; Unity; ROS; Gazebo; physics engine;

    Sammanfattning : Simulation software is becoming an increasingly important tool for automation systems both in industry and research. Within the field of mobile robotics, it is used to evaluate the performance of robots regarding localization, motion planning and control. LÄS MER

  5. 24. "Fat" Nanobeam-Waveguide Resonator for Suppressing Spectral Diffusion in InGaAs Quantum Dots

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Qinda Guo; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The coherent coupling of photons to solid state emitters is one of the building blocks for future quantum technology. However, one of the main sources for non-perfect or even strongly reduced coherence of the photons is charge noise which introduces energy shifts during or in between the photon emission events.

  7. 25. Simulation of Paperboard with the EBT Paperboard Model and Cohesive Zones

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Maria Anghel; [2019]
    Nyckelord :FEM; FEA; computer simulation; solid mechanics; paperboard; Technology and Engineering;

    Sammanfattning : Previous numerical investigations have simulated the delamination of paperboard using various mechanical and cohesive models. This has given satisfactory agreement between the simulation results and experimental data when comparing force-depth curves during creasing and moment-angle curves during folding. LÄS MER
