  1. 1. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    University essay from KTH/Tillämpad fysik

    Author : Alexandros Bampis; [2023]
    Keywords : Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Abstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE

  4. 3. Time Resolved Micro Photoluminescence of InGaN/GaN Quantum Dots

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Martin Eriksson; [2011]
    Keywords : ;

    Abstract : Time resolved micro photoluminescence of InGaN/GaN quantum dots has been investigated, together with power dependence and polarization measurements. The quantum dots are formed at the top of selectively grown GaN pyramids on a 4H-SiC substrate. Decay time constants in the range of 400 ps to 1. READ MORE

  5. 4. Growth and Characterization of ZnO Nanostructures

    University essay from Institutionen för fysik, kemi och biologi

    Author : Abdul Samad Syed; [2011]
    Keywords : PL photoluminescence ; Zinc Oxide ZnO ; optical properties; temperature dependent PL; Low temperature PL; Nanostructure; epitaxial film;

    Abstract : A close relation between structural and optical properties of any semiconductor material does exist. An adequate knowledge and understanding of this relationship is necessary for fabrication of devices with desired optical properties. READ MORE

  6. 5. Optical Spectroscopy of GaN/Al(Ga)N Quantum Dots Grown by Molecular Beam Epitaxy

    University essay from Institutionen för fysik, kemi och biologi

    Author : Kuan-Hung Yu; [2009]
    Keywords : Quantum dots; GaN; AlN; Exciton; Biexciton; micro-Photoluminescence.;

    Abstract : GaN quantum dots grown by molecular beam epitaxy are examined by micro-photoluminescence. The exciton and biexciton emission are identified successfully by power-dependence measurement. With two different samples, it can be deduced that the linewidth of the peaks is narrower in the thicker deposited layer of GaN. READ MORE
