The effect of diffraction on the self‐modulation of an intense laser beam in an initially uniform hydrogen plasma is investigated. A formalism is used in which the diffraction term in the paraxial wave equation can be arbitrarily reduced by the use of a weight factor ι. In the limit where ι...

Insights on local chemical structure of chalcogenide photovoltaic materials using solid state NMR spectroscopy
DownloadSpring 2023
Quaternary chalcogenides with the formula I2-II-IV-VI4 have emerged as promising candidates for photovoltaic materials, but many details about their structures remain poorly understood. This thesis describes the synthesis, structure determination, and optical properties of the sulfides Cu2MTtS4...
