    <title language="eng">Soft x-ray emission spectroscopy studies of the electronic structure of silicon supersaturated with sulfur</title>
    <abstract language="eng">We apply soft x-ray emission spectroscopy (XES) to measure the electronic structure of crystalline silicon supersaturated with sulfur (up to 0.7 at. %), a candidate intermediate-band solar cell material. Si L2,3 emission features are observed above the conventional Si valence band maximum, with intensity scaling linearly with S concentration. The lineshape of the S-induced features change across the insulator-to-metal transition, indicating a significant modification of the local electronic structure concurrent with the change in macroscopic electronic behavior. The relationship between the Si L2,3 XES spectral features and the anomalously high sub-band gap infrared absorption is discussed.</abstract>

    <title language="eng">Cu2ZnSnS4 thin-film solar cell absorbers illuminated by soft x-rays</title>
    <abstract language="eng">In view of the complexity of thin-film solar cells, which are comprised of a multitude of layers, interfaces, surfaces, elements, impurities, etc., it is crucial to characterize and understand the&#13;
chemical and electronic structure of these components. Because of the high complexity of the Cu2ZnSn(S,Se)4 compound semiconductor absorber material alone, this is particularly true for kesterite-based devices. Hence, this paper reviews our recent progress in the characterization of Cu2ZnSnS4 (CZTS) thin films. It is demonstrated that a combination of different soft x-ray spectroscopies is an extraordinarily powerful method for illuminating the chemical and electronic material characteristics from many different perspectives, ultimately resulting in a comprehensive picture of these properties. The focus of the article will be on secondary impurity phases, electronic structure, native oxidation, and the CZTS surface composition.</abstract>

    <title language="eng">Ultrafast Proton Dynamics in Aqueous Amino Acid Solutions Studied by Resonant Inelastic Soft X‑ray Scattering</title>
    <abstract language="eng">Resonant inelastic soft X-ray scattering (RIXS) has been used to study the&#13;
electronic structure of glycine and lysine in aqueous solution. Upon variation of the pH&#13;
value of the solution from acidic to basic, major changes of the nitrogen K edge RIXS data&#13;
are observed for both amino acids, which are associated with the protonation and&#13;
deprotonation of the amino groups. The experimental results are compared with&#13;
simulations based on density functional theory, yielding a detailed understanding of the&#13;
spectral changes, as well as insights into the ultrafast proton dynamics in the intermediate&#13;
core-excited/ionized state of the RIXS process.</abstract>
