TL;DR: In this paper, the authors demonstrate the synthesis and transfer of rhombohedral graphene with thickness up to 9 layers and areas up to ∼50μm2 using Raman spectroscopy.

TL;DR: In this article, the authors show several case studies of graphene characterization on a range of different substrates that highlight the versatility of THz-TDS measurements and its relevance for process optimization in graphene production scenarios.

TL;DR: In this paper, a graphene/Si heterojunction device has been realized to overcome many different requests necessary to make it a versatile, widely used and competitive detector, which can be used in different configurations that allow a high responsivity up to 107 A W-1, a rise time of a few nanoseconds, an external quantum efficiency greater than 300%, and a linear response for different light sources.
