Figure 3: PCDTBT scattering profiles along qz at various temperatures.

The scattering profiles along qz obtained at qr~0 (lower seven curves) and qr=0.15 Å−1 (top two curves). The dashed lines (black) are fits to a Gaussian profile. The blue 25 °C curve is measured before thermal treatment. The orange 25 °C curve is measured after thermal treatment.
