  1. 1. Investigation of Resistive Random Access Memory for 1T1R Nanowire Array Integration

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

    Författare :Orestes Theodoridis; [2020]
    Nyckelord :RRAM; Nanowire; Memory Technology; Nanoelectronics; Nanoscience; Physics and Astronomy;

    Sammanfattning : As modern electronics have started to reach its physical scaling limits, novel architectures and physics is needed to meet future demands. Oxide-based Resistive Random Access Memory (RRAM) is a new emerging technology that uses filament formation and rupture in thin oxides to generate resistive switching. LÄS MER

  3. 2. Simulations of a back scatter time of flight neutron spectrometer for the purpose of concept testing at the NESSA facility.

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Benjamin Eriksson; [2018]
    Nyckelord :fusion; JET; Geant4; NESSA; NESSA facility; back scatter tof; tof; time of flight; spectrometer; neutron; ITER; Monte Carlo; simulation;

    Sammanfattning : A back scatter time of flight neutron spectrometer consisting of two scintillation detectors is simulated in Geant4 to examine whether it is possible to perform a proof of concept test at the NESSA facility at Uppsala University. An efficiency of ε = 2.45 · 10^-6 is shown to be large enough for a neutron generator intensity of 1. LÄS MER

  4. 3. Exploring the Use of Graphene as a Target Material for Laser Plasma Ion Acceleration

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Författare :Hannes Pahl; [2017]
    Nyckelord :Laser Plasma Acceleration; Target Material; Graphene; Physics and Astronomy;

    Sammanfattning : The interaction of a solid target with an ultra-high intensity laser pulse can result in the laser plasma acceleration of ions. The recent proposal of a new laser plasma ion acceleration scheme, named chirped standing wave acceleration, has created interest in a new class of ultra-thin solid target materials, either freestanding or as a part of novel compound targets.

  5. 4. Monte Carlo simulations and measurements of the radiation environment at a laser-plasma accelerator

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Jack Strand Berg; [2016]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In current experiments at the high-power laser facility at the Lund Laser Centre, electrons accelerated to hundreds of MeV over short distances by means of laser wakefield acceleration in produced plasmas. To determine the amount of secondary radiation generated when accelerated electrons interact with surrounding materials is of interest to ensure a safe working environment. LÄS MER

  7. 5. Characterization of Terahertz Radiation Generated in an Organic Crystal

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Åsa Bengtsson; [2016]
    Nyckelord :Nonlinear optics; Terahertz radiation generation; Optical rectification; Difference frequency generation; Organic crystal; DSTMS; Physics and Astronomy;

    Sammanfattning : The terahertz region of the electromagnetic spectrum is an important research area allowing insights into fundamental science such as inter-molecular interactions, and with applications in the environmental, medical and security field. Using femtosecond lasers, it is possible to design compact and efficient terahertz generation schemes, resulting in few-cycle broadband pulses. LÄS MER
