Comparing local CMS spectra acquired in regions with DO ≈ 1 and DO < 0.2. Top panel: a scheme of the OFET device under local CMS light probe. b e-acc DO map (15 μm ×15 μm). c Schematics of charge transition dipole moment alignment (TDM): black circles indicate regions of DO ≈ 1 and DO < 0.2, whose TDM vector distribution is sketched in the drawing on the right side. d h-acc and e-acc spectra acquired in an area with DO ≈ 1. e e-acc local CMS spectra acquired in regions with, respectively, DO ≈ 1 and DO ≈ 0.2. f h-acc local CMS spectra acquired in the region with, respectively, DO ≈ 1 and DO ≈ 0.2 (OFET electron accumulation, e-acc: Vg = 30 V; Vpp = 40 ± 20 V; hole accumulation, h-acc: Vg = −30 V; Vpp = 40 ± 20 V; dashed lines, out-of-phase signal; degree of order, DO)
