Charge localization in polymeric metal-oxide-semiconductor capacitors

Charge enhancement of organic materials that was deduced more than two decades ago by means of capacitance-voltage (C-V) measurements meets with difficulties and controversial explanations when using the classical semiconductor theory. Experimentally, it has been found that the charge localization results in nonstationary and frequency-dependent behavior in the C-V measurements. Detailed analyses of the experimental results provide insight on …
