MgZnO-Based Negative Capacitance Transparent Thin-Film Transistor Built on Glass

IEEE Journal of the Electron Devices Society, 2021
We demonstrate the first wide bandgap oxide based negative capacitance transparent thin-film transistor (NC-TTFT) built on glass. The Mg0.03Zn0.97O (MZO) semiconductor served as the channel layer and ferroelectric Ni0.02Mg0.15Zn0.83O (NMZO) serves in the

Negative capacitance in a ferroelectric capacitor

Nature Materials, 2014
The Boltzmann distribution of electrons poses a fundamental barrier to lowering energy dissipation in conventional electronics, often termed as Boltzmann Tyranny. Negative capacitance in ferroelectric materials, which stems from the stored energy of phase transition, could provide a solution, but a direct measurement of negative capacitance has so far ...

Conditions for Domain-Free Negative Capacitance

IEEE Transactions on Electron Devices, 2023
While negative capacitance has been demonstrated in ferroelectric-dielectric heterostructures in the form of capacitance enhancement, all experimental evidence, to date, suggests the existence of domains therein. Here, we address the question: what are the conditions to achieve ideal, domain-free negative capacitance in ferroelectric-dielectric ...

Current Prospects and Challenges in Negative-Capacitance Field-Effect Transistors

IEEE Journal of the Electron Devices Society, 2023
For decades, the fundamental driving force behind energy-efficient and cost-effective electronic components has been the downward scaling of electronic devices. However, due to approaching the fundamental limits of silicon-based complementary metal-oxide-

Revisiting the Theory of Ferroelectric Negative Capacitance [PDF]

IEEE Transactions on Electron Devices, 2016
In this paper we revisit the theory of negative capacitance, in a (i) standalone ferroelectric, (ii) ferroelectric-dielectric, and (iii) ferroelectric-semiconductor series combination, and show that it is important to minimize the total Gibbs free energy of the combined system (and not just the free energy of the ferroelectric) to obtain the correct ...

Investigation of Negative DIBL Effect and Miller Effect for Negative Capacitance Nanowire Field-Effect-Transistors

IEEE Journal of the Electron Devices Society, 2020
In this study, the negative DIBL (N-DIBL), negative differential resistance (NDR), and Miller effect of a negative capacitance nanowire filed-effect-transistor (negative capacitance (NC) NWFET) were analyzed by employing the custom-built SPICE model.

Strain control of layer-resolved negative capacitance in superlattices

npj Computational Materials, 2020
Negative capacitance in BaTiO3/SrTiO3 superlattices is investigated by Monte Carlo simulations in an atomistic effective Hamiltonian model, using fluctuation formulas for responses to the local macroscopic field that incorporates depolarizing fields.
