Fig. 1: Ambipolar FET characteristics for DPPT-TT, AN, and NN at room temperature.
From: Spin relaxation of electron and hole polarons in ambipolar conjugated polymers
a–c The chemical structures of the three molecules used for this study: DPPT-TT, AN, and NN, respectively. d–f Device transfer curves in both the linear and saturation regimes. Red corresponds to holes and blue to electrons. In all plots, the upper, v-shaped trace corresponds to the saturation regime (as expected for ambipolar performance). g–i Corresponding mobilities (where, for clarity, mobilities before the turn-on voltage are not shown). The open (filled) symbols in correspond to the linear (saturation) mobilities.
