Negative Capacitance beyond Ferroelectric Switches [PDF]
ACS Applied Materials & Interfaces, 2018 Negative capacitance transistors are a unique class of switches capable of operation beyond the Boltzmann limit to realize subthermionic switching. To date, the negative capacitance effect has been predominantly attributed to devices employing an unstable insulator with ferroelectric properties, exhibiting a two-well energy landscape, in accordance ...

Negative Capacitance for Electrostatic Supercapacitors [PDF]
Advanced Energy Materials, 2019 AbstractThe increasing demand for efficient storage of electrical energy is one of the main challenges in the transformation toward a carbon neutral society. While electrostatic capacitors can achieve much higher power densities compared to other storage technologies like batteries, their energy densities are comparatively low. Here, it is proposed and

Evaluation of the differential capacitance for ferroelectric materials using either charge-based or energy-based expressions [PDF]
Journal of Advanced Dielectrics, 2014 Differential capacitance is derived based upon energy, charge or current considerations, and determined when it may go negative or positive. These alternative views of differential capacitances are analyzed, and the relationships between them are shown ...
