  1. 16. Manipulation of thin metal film growth on weakly-interacting substrates using gaseous surfactants

    Master-uppsats, Linköpings universitet/Nanodesign

    Författare :Martin Konpan; [2019]
    Nyckelord :Surface physics; material science;

    Sammanfattning : Thin films are structures with thicknesses ranging from the atomic scale to the mesoscale that are used to alter the properties of a surface and/or serve as functional layers in devices. Thin metal films deposited from the vapor phase on weakly-interacting substrates, including oxides (TiO2, ZnO, SiO2 etc. LÄS MER

  3. 17. A computational study on indium nitride ALD precursors and surface chemical mechanism

    Master-uppsats, Linköpings universitet/Kemi

    Författare :Karl Rönnby; [2018]
    Nyckelord :Computational Chemistry; Chemical Vapour Deposition; Atomic Layer Deposition; Indium nitride; gas phase decomposition; surface mechanism;

    Sammanfattning : Indium nitride has many applications as a semiconductor. High quality films of indium nitride can be grown using Chemical Vapour Deposition (CVD) and Atomic Layer Deposition (ALD), but the availability of precursors and knowledge of the underlaying chemical reactions is limited.

  4. 18. Ultra-Thin Ag Films on the Sn/Si(111)-√3×√3 Surface Studied by STM

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Rasmus Lavén; [2018]
    Nyckelord :Silver; Silicon; Tin; Metal-semiconductor interfaces; Thin metal films; Scanning tunneling microscopy; Quantum size effects;

    Sammanfattning : The growth of atomically flat silver films on Si(111) usually requires a two-step growth, including deposition at low temperature (≈100 K) followed by slowly annealing to room temperature. In addition, flat silver films are usually only obtained on Si(111) for film thicknesses larger than the critical thickness of 6 monolayer. LÄS MER

  5. 19. Electro-Optical Characterization of Passivated InAsP/InP Quantum Discs-in-Nanowire Heterostructures

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

    Författare :Samareh Kordi Jazi; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Semiconductor nanowires, with their quasi one-dimension geometry, inherently provide strain relaxation for heterogeneous integration and also strong light mode confinement. Nanowire-based photonic devices have also been demonstrated to offer significantly enhanced quantum efficiency, gain and reduced noise. LÄS MER

  7. 20. SnOx electron selective layers for perovskite/silicon tandem solar cells using atomic layer deposition

    Master-uppsats, KTH/Energiteknik

    Författare :Lisa Anna Zafoschnig; [2018]
    Nyckelord :;

    Sammanfattning : In this work the application of ALD deposited SnOx films as electron transport layers in perovskite solar cells is analysed. Processes to fabricate homogeneous, transparent and conductive tin oxide films were developed on an Oxford Instruments FlexAL tool using a TDMASn precursor and H2O as oxidiser. LÄS MER
