Fig. 1. SEM micrographs and Raman signals of uncoated and coated GaN-microrods.

Fig. 1

a Uncoated and b conformally coated microrods with organic PEDOT deposited via oxidative chemical vapor deposition (oCVD). c Nonconformal coverage of GaN-microrods with PEDOT:PSS via spin-coating in which surface tension effects lead to liquid bridging between three adjacent microrods (secondary electron map, tilt = 30°/0°, EPE = 5 kV, scale bars correspond to 1 µm). d Corresponding Raman signals reveal the characteristic GaN peak (dashed, black) and PEDOT peaks (dotted blue) for the coated microrods.
