  1. 11. Heteroepitaxial Growth of GaN Film on Si substrate by Magnetron Sputtering

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Zahra Mohammadianrasnani; [2023]
    Nyckelord :GaN; Sputter epitaxy; Thin film;

    Sammanfattning : In this study, the effect of AlN buffer layer structure and morphology on the GaN films deposited on Si (111) substrate by reactive DC magnetron sputtering have been studied. For structural and morphological characterization X-ray diffraction (XRD) and Scanning electron microscope (SEM) were used. LÄS MER

  3. 12. Optical properties in chalcogenide glasses and their temperaturedependence. : Literary survey and experiments.

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Matilda Karlsson; Saifallah Khaled Ali; Erik Lundqvist; Ask Löthman Ybo; Kalle Sigås; Oscar Törnquist; [2023]
    Nyckelord :Chalcogenide materials; Chalcogenide glass; Optical properties; Temperature dependence;

    Sammanfattning : This study aimed to investigate methods for determining the temperature dependence of the refractive index and absorption of IR-transparent materials through literary studies and experimental tests. Results from the experimental trials were hard to obtain due to the inherent difficulty of measuring optical properties and yielded only temperature trends of transmittance and reflectance. LÄS MER

  4. 13. Comparison and optimization of extracellular vesicle (EV) capturing on functional thin films for their molecular profiling

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Prattakorn Metem; [2023]
    Nyckelord :extracellular vesicle; plasmonic nanohole array; atomic force microscopy; fluorescence analysis; extracellulära vesiklar; nanohålsuppsättning; atomkraftsmikroskopi; fluorescensanalys;

    Sammanfattning : Extracellular vesicles (EVs) are lipid bilayer encapsulated nanoparticles which have emerged as an excellent source of biomarkers for multiple diseases, including cancer. However, they are highly heterogeneous in their molecular compositions which remains a major challenge hindering the utilization of their biomarker potential. LÄS MER

  5. 14. Thin Indium Tin Oxide Layer Development for Crystalline Silicon/Perovskite Two Terminal Tandem Solar Cell

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Aravind Srinivasachari; [2023]
    Nyckelord :Indium Tin Oxide; Thin-film characterisation; Magnetron Sputtering; Screen printing; Tandem Solar Cells; Indium-tennoxid; karaktärisering av tunnfilm; magnetronförstoftning; screentryck; tandemsolceller;

    Sammanfattning : ITO is widely regarded as the optimal TCO for serving as front window layer in PSK/c-Si tandem solar cells. It is known to effectively mitigate several stability issues present in perovskite solar cells while demonstrating excellent lateral conductivities and optical transparency across the entire solar spectrum.

  7. 15. Improving polarizing neutron optics by introducing 11B4C as interlayers

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Martin Falk; [2023]
    Nyckelord :Thin film multilayers; Neutron optics; Neutron polarization;

    Sammanfattning : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. LÄS MER
