Figure 1. Illustration for the device structure of LC-on-OFET sensory devices and their operation.

Figure 1

(a) Operation of the LC-on-OFET sensory devices upon nitrogen gas flow stimulation; (left) generation of charges in the P3HT layer by the strong dipoles of LC molecules, (right) change of the induced charges by the gas flow stimulation owing to the collective movement of LC molecules. (b) Materials used for the fabrication of the LC-on-OFET sensory devices. (c) SEM (top) and NanoView (bottom) images for the surface of the OFET device which is fully covered by the P3HT layer (note that a 60 nm-thick silver layer was additionally coated on the P3HT layer of the device for the NanoView measurement). ‘S' and ‘D' denote source and drain electrodes, respectively.
