Sommario/riassunto

Diese Arbeit systematisiert die bereits im Jahr 2005 eingeführten brasilianischen Stromauktionen erstmals umfassend und bewertet sie anhand von Experteninterviews und empirischen Erhebungen. Aus dem funktionalen Rechtsvergleich mit dem deutschen Ausschreibungsmodell ergeben sich wesentliche Erkenntnisse für das EEG 2017 im Bereich der Technologieoffenheit und der Realisierungsquote bezuschlagter Projekte. Denn die EEG-Ausschreibungen verstoßen infolge niedriger Teilnehmerzahlen in weiten Teilen gegen die unionsrechtliche Vorgabe der EE-Richtlinie 2018 zur wettbewerbsorientierten Vergabe von Fördermitteln. Zudem verfehlen sie die national gesetzten Ausbauziele. Als Lösungsvorschlag wird ein auf den brasilianischen Vorschriften basierender Regelungsentwurf zur automatischen technologieübergreifenden Umverteilung der ausgeschriebenen Leistung erarbeitet. Ferner zeigt diese Arbeit auf, dass die Regelungen des EEG 2017 Projektabbrüche kaum sanktionieren. Daher sollte erwogen werden, nach brasilianischem Vorbild Projektabbrüche mit dem Ausschluss von zukünftigen Ausschreibungen zu pönalisieren. A functional legal comparison of German renewable energy auctions, introduced comprehensively in 2017, with Brazilian energy auctions, introduced



already in 2005, provides relevant insights for the German system. This work offers the first comprehensive systematisation of relevant Brazilian regulations, and assesses their effectiveness using expert interviews and empirical analysis. It highlights several solutions to problems regarding technology neutral auctions and the realisation rate of successful projects, that could be valuable for the German model. Due to low participant numbers, many German energy auctions violate the european energy directive of 2018, which states that the awarding of funding must be competition-oriented. This work proposes a solution to this problem, based on a similar mechanism adopted by Brazilian regulations, which automatically redistributes tendered capacity across different technologies. Legal comparisons made in this work demonstrate that project cancellations in Germany are not sanctioned sufficiently. As such, to ensure that expansion targets are met, it is worth considering following the Brazilian example of sanctioning project cancellations by limiting participation in future auctions.

Sommario/riassunto

This concise book offers an essential introduction and reference guide for the many newcomers to the field of physics of elemental 2D materials. Silicene and related materials are currently among the most actively studied materials, especially following the first experimental synthesis on substrates in 2012. Accordingly, this primer introduces and reviews the most crucial developments regarding silicene from both theoretical and experimental perspectives. At the same time the reader is guided through the extensive body of relevant foundational literature. The text starts with a brief history of silicene, followed by a comparison of the bonding nature in silicon versus carbon atoms. Here, a simple but robust framework is established to help the reader follow the concepts presented throughout the book. The book then presents the atomic and electronic structure of free-standing silicene, followed by an account of the experimental realization of silicene on substrates. This topic is subsequently developed further to discuss various reconstructions that silicene acquires due to interactions with the substrate and how such effects are mirrored in the electronic properties. Next the book examines the dumbbell structure that is the key to understanding the growth mechanism and atomic structure of multilayer silicene. Last but not least, it addresses similar effects in other elemental 2D materials from group IV (germanene, stanane), group V (phosphorene) and group III (borophene), as well as transition metal dichalcogenides and other compositions, so as to provide a general comparative overview of their electronic properties.
