Perspective on terahertz spectroscopy of graphene
Max Planck Institute for Polymer Research - Ackermannweg 10, D-55128 Mainz, Germany

Accepted: 7 September 2015
Graphene has been an intensely studied material, owing to its unique band structure and concomitant outstanding electronic properties. In the past decades, ultrafast terahertz (THz) spectroscopy has developed into a powerful tool to characterize ultrafast charge carrier dynamics in a wide range of materials and material structures. In this Perspective we review recent experimental work exploring the ultrafast electron dynamics in graphene in the THz spectral range, and present a simple thermodynamic picture describing the THz linear, nonlinear, and photo-induced conductivity of this remarkable material.
