  1. 1. Mission Concept for a Satellite Mission to Test Special Relativity

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Volkan Anadol; [2016]
    Keywords : BOOST; Special Relativity; Kennedy Thorndike; Eclipse duration; Ground visibility; Downlink feasibility; 3-axis stabilization; Spin stabilized satellite; Solar array estimation; Battery size estimation.;

    Abstract : In 1905 Albert Einstein developed the theory of Special Relativity. This theory describes the relation between space and time and revolutionized the understanding of the universe. While the concept is generally accepted new experimental setups are constantly being developed to challenge the theory, but so far no contradictions have been found. READ MORE

  3. 2. Magneto-optical studies of optical spin injection in InAs quantum dot structures

    University essay from Funktionella elektroniska material; Tekniska högskolan

    Author : Wang Po-Hsiang; [2012]
    Keywords : optical spin injection; optical orientation spectroscopy; magnetic field; Landau level; hyperfine interaction; dynamic nuclear polarization; InAs GaAs quantum dots;

    Abstract : Optical spin injection in InAs/GaAs quantum dots (QDs) structures under cryogenic temperature has been investigated in this work using continuous-wave optical orientation spectroscopy. Circularly polarized luminescence from trions in the QDs was used as a measure for the degree of spin polarization of the carriers in the QD ground states. READ MORE

  4. 3. Polymer electrochromism and surface plasmons combined on metallic diffraction gratings

    University essay from Institutionen för teknik och naturvetenskap

    Author : Jérôme Garnier; [2008]
    Keywords : Conducting polymers; electrochromism; surface plasmons; PEDOT-PSS; PEDOT-S;

    Abstract : All conducting polymers are potentially electrochromic, owing to the injection of charge carriers that changes their electronic structure and results in a shift of their optical absorption towards higher wavelengths. PEDOT-PSS and PEDOT-S are very promising materials in terms of electrochromic properties, due to the good contrast existing between their doped and undoped forms. READ MORE
