Figure 4: Power absorption of the ultrafast electric field signal, retained electronic heat and carrier temperatures.
From: Thermodynamic picture of ultrafast charge transport in graphene
Measured (blue symbols), and predicted by the time-dependent thermodynamic model (blue solid line), integrated power absorption of graphene as function of peak THz field. Red area: the integrated energy retained in electronic system of graphene as a result of interaction with the THz field, provided by the model. The corresponding average and peak (in brackets) electron temperatures Tel for selected peak THz fields are indicated in the figure. The error bars are the s.d. in the measurements.
