Scatter Plot from Scientific Research

Isolated contributions of phonon-mode-resolved EPC at the electron energy of 2.05 eV to the 2D EPC spectrum S EPC,norm of MAPI measured at temperatures of 3.7 K, 50 K, 140 K and 200 K. The symbols indicate the experimental values, averaged over the electronic (phonon) energy range of ~0.01 eV (~0.1 THz), and the error bars indicate the standard deviation of more than 100 data points over the range.
