    Sammanfattning : Partial discharge (PD) detection is a powerful tool to diagnose the defects and degradation in high voltage electrical insulation systems. It can be performed in both on-line and off-line conditions. LÄS MER

  5. 24. Singlet Fission - The Effects of Solvent Polarity and Conformation

    Författare :Rasmus Ringström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Singlet fission; rotational conformation; photoinduced electron transfer; transient absorption;

    Sammanfattning : Singlet fission (SF) is a process in which one initial high energy singlet excited state is converted into two triplet excited states of roughly half the energy of the initial state. This process has the potential to increase the efficiency of conventional solar cells by modifying the energy of the incident solar radiation to better match the energy input required to generate electricity.

  7. 25. Synchrotron light based spectroscopy of MBE-grown (GaMn)As structures

    Författare :Johan Adell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Diluted magnetic Semiconductor; GaMn As; UPS; XAS; XPS; RPES;

    Sammanfattning : Structures based on the diluted magnetic semiconductor (GaMn)As have been grown by low temperature molecular beam epitaxy and studied using synchrotron radiation based electron spectroscopy. An investigation of modifications due to in situ low temperature annealing under amorphous As capping has been performed. LÄS MER
