  1. 1. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

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

    Författare :Yoana Ilarionova; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. LÄS MER

  3. 2. Quantum signatures in the work fluctuation-dissipation relation protocol

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Jian Li; [2023]
    Nyckelord :Quantum entanglement; fluctuation; coherence; quantum information; quantum thermodynamics; Physics and Astronomy;

    Sammanfattning : Quantum thermodynamics deals with the behavior of thermal machines that operate in the quantum regime, where coherences and entanglement can have a significant impact. However, detecting such quantum effects in thermal machines can be challenging, as they are primarily manifested as fluctuations. LÄS MER

  4. 3. Temperature Dependent Electrical Characterisation of Vertical InAs-InGaAs Nanowire MOSFETs

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Sofie Johannesson; Sebastian Skog; [2022]
    Nyckelord :Vertical InGaAs Nanowire MOSFET Temperature Dependence Noise; Technology and Engineering;

    Sammanfattning : This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults).

  5. 4. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

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

    Författare :Klára Nováková; [2021]
    Nyckelord :perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

    Sammanfattning : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

  7. 5. 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
