abstract
The transient response of negative capacitance (NC) in an organic ferroelectric capacitor is experimentally investigated. To observe the transient response of the NC, a simple series network, consisting of an external series resistor and an organic ferroelectric capacitor, is built. The Landau coefficients of the organic ferroelectric capacitor were extracted from the measured polarization versus applied electric field data. A circuit level simulation was provided with the extracted parameters based on the Landau-Khalatnikov equation. To explore the impact of the RC time constant on the NC time duration in the RC series circuit, the external series resistor is altered as a tuning parameter. Also, the effect of various temperatures of the ferroelectric capacitor on the NC time duration is experimented. This paper demonstrates that either the external resistor or the ambient temperature can change the NC time duration in an organic ferroelectric capacitor.
