  1. 1. Electronic Structure of π-Conjugated Materials and Their Effect on Organic Photovoltaics

    Author : Chuanfei Wang; Mats Fahlman; Xianjie Liu; Ergang Wang; Zong-Xiang Xu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The great tunability of structure and electronic properties of π-conjugated organic molecules/polymers combined with other advantages such as light weight and flexibility etc., have made organic-based electronics the focus of an exciting still-growing field of physics and chemistry for more than half a century.

  2. 2. Free charge carrier properties in group III nitrides and graphene studied by THz-to-MIR ellipsometry and optical Hall effect

    Author : Nerijus Armakavicius; Vanya Darakchieva; Philipp Kühne; Stefan Zollner; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Development of silicon based electronics have revolutionized our every day life during the last five decades. Nowadays silicon based devices operate close to their theoretical limits that is becoming a bottleneck for further progress. READ MORE

  3. 3. The diagnostic potential of the He I D3 spectral line in the solar atmosphere

    Author : Tine Libbrecht; Jaime de la Cruz Rodríguez; Jorrit Leenaarts; Göran Scharmer; Valentín Martínez Pillet; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sun; Line formation; Chromosphere; Spectro-Polarimetry; Flares; Reconnection; Astronomy; astronomi;

    Abstract : The research question of my PhD is in a way a simple one: what can observations of the He I D3 line teach us about the solar chromosphere? This optical spectral line at 5876 Å is generally formed in the upper chromosphere, and is sensitive to the local magnetic field. The He I D3 line is also indirectly sensitive to heating of the transition region and corona, since it is resulting from a transition that occurs between levels in the triplet system of neutral helium.

  4. 4. Experimental study of phase separation in Fe-Cr based alloys

    Author : Jing Zhou; John Ågren; Joakim Odqvist; Peter Hedström; Andersson Marcus; KTH; []
    Keywords : Duplex stainless steels; Ferritic stainless steels; Spinodal decomposition; Phase separation; Atom probe tomography; Clustering; Radial distribution function RDF ;

    Abstract : Duplex stainless steels (DSSs) are important engineering materials due to their combination of good mechanical properties and corrosion resistance. However, as a consequence of their ferrite content, DSSs are sensitive to the so-called ‘475°C embrittlement’, which is induced by phase separation, namely, the ferrite decomposed into Fe-rich ferrite (α) and Cr-rich ferrite (α'), respectively.
