Over the last century, numerous optical techniques have been developed to characterize materials, giving insight into their optical, electronic, magnetic, and structural properties and elucidating such diverse phenomena as high-temperature superconductivity and protein folding. Optical Techniques for Solid-State Materials Characterization provides detailed descriptions of basic and advanced optical techniques commonly used to study materials, from the simple to the complex. The book explains how to use these techniques to acquire, analyze, and interpret data for gaining insight into material properties. With chapters written by pioneering experts in various optical techniques, the text first provides background on light–matter interactions, semiconductors, and metals before discussing linear, time-integrated optical experiments for measuring basic material properties, such as Fourier transform infrared spectroscopy, photoluminescence, and Raman scattering. The next section begins with a description of ultrashort pulse generation and carrier dynamics in semiconductors and metals. The book then discusses time-resolved optical techniques, such as pump–probe spectroscopy, terahertz spectroscopy, and magneto-optical spectroscopy. The subsequent section describes spatially resolved optical spectroscopy, including conventional optical microscopy and micro-optical and near-field scanning techniques. The book concludes with an overview of more advanced, emerging optical techniques, such as ultrafast x-ray and electron diffraction, ultrafast photoemission spectroscopy, and time-resolved optical microscopy. As optical techniques are among the first applied when studying new systems with novel properties, the information presented in this comprehensive reference will only grow in importance. By supplying clear, detailed explanations of these techniques, the book enables researchers to readily implement them and acquire new insights into the materials they study.

Dieses Buch präsentiert Ergebnisse der Grundlagenforschung an Graphen. Nach einer kritischen Auseinandersetzung mit dem Begriff des Graphen-Zeitalters werden zwei Studien aus dem Bereich der Kurzzeitspektroskopie im mittleren Infrarotbereich vorgestellt. Eine konsistene Reihe von Herleitungen vermittelt didaktisch die benötigten Grundlagen zum Einstieg in die Forschungsarbeiten. Durch die Verwendung des Freie-Elektronen-Lasers FELBE in einem Photonenergiebereich unterhalb der optischen Phononenergie in Graphen von 200 meV kann in diesen Studien die Streuung der Ladungsträger mit diesen Phononen effizient unterdrückt werden. Hierdurch wird ein unverstellter Blick auf die verbleibenden Prozesse der Ladungsträgerdynamik freigegeben. In einer ersten Studie wird so mittels polarisationsaufgelöster Anregungs-Abfrage-Experimente die zuvor weit verbreitete Hypothese einer universell gültigen nahezu instantanen Thermalisierung einer optisch induzierten Nichtgleichgewichtsverteilung des elektronischen Systems widerlegt. In einer zweiten Studie werden durch entartetes Vier-Wellen Mischen in Landau-quantisiertem Graphen die nichtlinearen optischen Eigenschaften dieses Materials nachgewiesen. Während die gemessenen Nichtlinearitäten in Graphen unter Abwesenheit magnetischer Felder den Erwartungen bislang nicht gerecht werden, konnte hier für Landau-quantisiertes Graphen die Größenordnung der Suszeptibilität dritter Ordnung, sowie das Resonanzverhalten experimentell im Einklang mit den Vorhersagen bestätigt werden. Beide Studien leisten so einen entscheidenden Beitrag zum Verständnis der Ladungsträgerdynamik in Graphen.
