Study of graphene’s properties for the optimization of graphene-based electronic devices
Abstract:
The discovery of graphene, has stimulated a huge amount of interest in the material science community, and its properties have the potential to revolutionize many fields, from basic to applied research.
One of the first application where such exceptional properties have improved the state of the art is resistance metrology. The anomalous integer quantum Hall effect discovered in graphene has already led to an improvement of one order of magnitude of the quantization accuracy, thanks to the huge spacing between the first Landau levels. Moreover, such results promise for the development of resistance standards working at non cryogenic temperatures, with great advantages for industrial applications.
In this seminar I’ll show the status of graphene research at the INRIM(Italian Institute for Metrological Research) aimed to the optimization of QHE devices. I’ll also show how these efforts towards devices optimization have led to interesting results in the fundamental research of graphene’s physics.
