Negative Capacitance Based on Isomeric Polythiophene in Action In this study, we demonstrated that arranging positive and negative capacitance materials in series, based on isomeric polythiophene, led to a notable increase in total capacitance. Furthermore, the application of negative capacitance (NC) technology in supercapacitors (SCs) construction offers the potential for energy storage capabilities surpassing fundamental limits.

Isomeric Polythiophene: Promising Material for Low Voltage Electronic Devices In this investigation, we present empirical observations detailing the manifestation of substantial negative capacitance (NC), reaching up to -1F, within iodine-doped isomeric polythiophene (IPTh-I2). NC observed in our case is not transient but stable enough to be measured for as long as the optimum concentration of iodine dopant is available.
