  1. 6. Investigations of p-type quantum dots in GaSb nanowires

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

    Författare :In-Pyo Yeo; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. LÄS MER

  3. 7. Closed-Loop Control of a 3D Printed Soft Actuator with Soft Position Sensors

    Master-uppsats, KTH/Mekatronik

    Nyckelord :Soft Actuators; 3D Printing; Closed-Loop Control; Strain Sensor; Soft Gripper; Mjuka Ställdon; 3D-Skrivning; Återkopplad Kontroll; Töjningssensor; Mjukt Gripdon;

    Sammanfattning : This thesis performs closed-loop control of a 3D printed soft bending actuator with feedback from a 3D printed strain sensor. This process utilizes the Finite Element Method (FEM) to design a bellow type pneumatic bending actuator that can handle pressures up to 4 bar. LÄS MER

  4. 8. Design, synthesis and characterization of Dimethylammonium / Ethylammonium / Cesium Lead  Halide Perovskites for optoelectronic applications

    Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Elin Ljungström; Ellen Hådén; Lukas Lekberg; Nima Taherpour; [2020]
    Nyckelord :Perovskit; solcell; perovskitsolcell; halvledare; organiska oorganiska perovskiter;

    Sammanfattning : The world is facing a climate crisis and to be able to solve it society needs to decrease the use of fossil fuels and find renewable alternatives. Solar energy is a great contender for a renewable energy source since it can be harvested for eternal time. LÄS MER

  5. 9. Optimization of Heat Exhaust in the Edge of Tokamaks via Controlled Magnetic Stochastization

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Amit Kharwandikar; [2020]
    Nyckelord :Resonant Magnetic Perturbations; Tokamak; Divertor; Steady-state heat deposition; Power exhaust; Perturbation optimization; Resonant magnetiska störningar; Tokamak; avledare; statisk värmeavledning; värmeavledningen; störningsoptimering;

    Sammanfattning : The protection of plasma facing components from heat and particle overloads is paramount to ensure the operability and desired lifetime of magnetic fusion devices. The possibility of using external 3D magnetic perturbations to improve the steady-state heat exhaust in diverted tokamaks has been studied in this thesis. LÄS MER

  7. 10. Synthesis of single-layer graphene and studying oxidation behaviour of copper foil.

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Mouna Rafei; [2020]
    Nyckelord :;

    Sammanfattning : The ultimate aim of the current study is to investigate the electron transfer from copper (Cu) to single layer graphene through a thin Cu oxide layer. Therefore the project is divided into two main parts. LÄS MER
