(a) AFM image of the CdSe nanoparticles embedded in the layer and (b) a cross-sectional analysis of the selected region between the two arrows shown in (a). The region between the dashed lines corresponds to the CdSe nanoparticle.
Current-voltage curves for the nanoparticles embedded in the PVK, PS, or polymer layer/ITO devices.
Schematics of the electronic structures corresponding to the operating mechanisms of the charge-capturing and the charge-storing processes for the nanoparticles embedded in the polymer layer/ITO/glass device under a positive bias voltage. The energy levels for the CdSe nanoparticles are taken from Ref. 15, and those for the PVK and the PS layer are taken from Refs. 16 and 17, respectively.
Capacitance-voltage curve for the nanoparticles embedded in the hybrid polymer layer/ITO device.
The on/off ratios of characteristics and the flatband voltage shifts of characteristics for the OBD with various active polymer matrices.
