  3. 12. Plasmonic Effect of Metal Nanoparticles Deposited on Wide-Band Gap Metal Oxide Nanowire Substrate

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mojtaba Gilzad Kohan; [2017]
    Keywords : plasmonic particles; nano wires; wide band gap semiconductors;

    Abstract : The application of nanowires (NWs) in solar cells (SCs) is of great interest due to their new promising aspects established in nanoelectronics. Semiconductors associated with plasmonic metal nanoparticles (NPs) such as Silver (Ag), Gold (Au) and Copper (Cu), show enhanced performance in solid state light absorbing SCs owing to plasmonic characteristic of noble metal NPs.

  4. 13. Selective Plane Illumination Microscopy Using Non-spreading Airy Beams

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Aleksandrs Leitis; [2016]
    Keywords : Microscopy; Selective Plane Illumination Microscopy; Light Sheet Microscopy; Physics and Astronomy;

    Abstract : Recently a new field of microscopy has emerged, known as selective plane illumination microscopy (SPIM). Using a SPIM setup the sample is illuminated with a thin light sheet from the side. The selective plane illumination overcomes many problems that conventional microscopes have. READ MORE
