  4. 3. Dopant diffusion in Si and SiGe

    Författare :Jens S. Christensen; KTH; []
    Nyckelord :condensed matter;

    Sammanfattning : Dopant diffusion in semiconductors is an interestingphenomenon from both technological and scientific points ofview. Firstly, dopant diffusion is taking place during most ofthe steps in electronic device fabrication and, secondly,diffusion is related to fundamental properties of thesemiconductor, often controlled by intrinsic point defects:self-interstitials and vacancies.

    Sammanfattning : Organic semiconductors may enable a wide range of flexible electronics, such as flexible displays or solar cells. Conjugated polymers constitute one of the most widely studied class of organic semiconductors. LÄS MER

  7. 5. Correlating Nanostructure and Electronic Properties of Organic Semiconductors by Electron Microscopy

    Författare :Gustav Persson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D; transmission electron microscopy; clustering; molecular dopant; nanostructure; structure-property correlation; visualisation; concentration; organic semiconductor;

    Sammanfattning : Organic semiconductors enable fabrication and efficient processing of electronic devices with light weight, mechanical flexibility and tuneable properties. Despite significant progress in the last decades, efficiencies and long-term stabilities of these systems still need to be improved. LÄS MER
