      Elektronische und dielektrische Eigenschaften von Graphen und Graphenoxid

      Überlegene elektronische und dielektrische Eigenschaften von gewelltem elektrochemisch reduziertem Graphen gegenüber Graphenoxidpapier

      • 88 pages
      • 4 hours of reading

      Die Arbeit untersucht die überlegenen frequenz- und temperaturabhängigen elektronischen sowie dielektrischen Eigenschaften von elektrochemisch reduziertem Graphen (ERGO) im Vergleich zu Graphenoxidpapieren (GO). ERGO zeigt eine stärkere Polarisierung, bedingt durch eine höhere Konzentration reduzierter Cluster. Während GO eine größere Frequenzabhängigkeit aufweist, steigt die dielektrische Permittivität von ERGO mit abnehmender Frequenz. Hohe Frequenzen führen zu größeren Leitungsverlusten in ERGO. Zudem wird die temperaturabhängige Leitfähigkeit durch thermisch aktivierten Transport und ionische Streuung von Ladungsträgern beeinflusst.

      Electronic and Dielectric Properties of Graphene and Graphene Oxide

      Superior Electronic and Dielectric Properties of Corrugated Electrochemically Reduced Graphene over Graphene Oxide Paper

      • 84 pages
      • 3 hours of reading

      The study reveals that electrochemically reduced graphene (ERGO) exhibits significantly superior electronic and dielectric properties compared to graphene oxide (GO), with enhancements by two orders of magnitude. This improvement is attributed to stronger polarization from reduced clusters and thinner sheets in ERGO, while GO's properties are influenced by interlayer O-H bonds. The research also discusses how dielectric permittivity varies with frequency and temperature, highlighting the transition from a graphene-ion-cloud to a graphene-air dielectric system at elevated temperatures.
