  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

  3. 2. E-Band SPDT RF Switch for a Class F PA in III-V Nanowire MOSFET Technology

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Rungeng Xu; [2022]
    Keywords : E-band; III-V Nanowire MOSFET; RF Switch; Class-F PA; Technology and Engineering;

    Abstract : This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. READ MORE

  4. 3. Evaporation Duct Modelling for a Wave-Propagation Simulator

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Oscar Eklund; [2022]
    Keywords : evaporation; duct; height; monin; obukhov; mos; surface; layer; ssft; byc; pj; businger; dyer; beljaars; holtslag; cheng; brutsaert; sheba;

    Abstract : Long-range communication proves to be a challenge due to the Earth’s curvature, since electromagnetic waves propagate away from the Earth’s surface in a free atmosphere. A possible solution to beyond line-of-sight communication is the atmospheric phenomenon known as the evaporation duct. READ MORE

  5. 4. Do fathers care? Examining caring experiences of Ugandan transnational fathers in Gothenburg Sweden.

    University essay from Göteborgs universitet/Institutionen för socialt arbete

    Author : Rogers Mpaata; [2021-02-25]
    Keywords : fatherhood; perceptions; transnational; caring; children;

    Abstract : The purpose of the study is to explore caring experiences of transnational Ugandan fathers in Gothenburg Sweden based on their caring lived realities taking in account of their understanding of care. The aims of the study are to examine the perception and interpretation of childcaring by transnational fathers, analyse ways in which fathers were able to put their perceptions into practice and resource mechanisms that have facilitated their dealing with feelings of imperfection in child caring.
