Query: Physical Mechanism behind the Hysteresis-free Negative Capacitance
  Effect in Metal-Ferroelectric-Insulator-Metal Capacitors with Dielectric
  Leakage and Interfacial Trapped Charges   The negative capacitance (NC) stabilization of a ferroelectric (FE) material
can potentially provide an alternative way to further reduce the power
consumption in ultra-scaled devices and thus has been of great interest in
technology and science in the past decade. In this article, we present a
physical picture for a better understanding of the hysteresis-free charge boost
effect observed experimentally in metal-ferroelectric-insulator-metal (MFIM)
capacitors. By introducing the dielectric (DE) leakage and interfacial trapped
charges, our simulations of the hysteresis loops are in a strong agreement with
the experimental measurements, suggesting the existence of an interfacial oxide
layer at the FE-metal interface in metal-ferroelectric-metal (MFM) capacitors.
Based on the pulse switching measurements, we find that the charge enhancement
and hysteresis are dominated by the FE domain viscosity and DE leakage,
respectively. Our simulation results show that the underlying mechanisms for
the observed hysteresis-free charge enhancement in MFIM may be physically
different from the alleged NC stabilization and capacitance matching. Moreover,
the link between Merz's law and the phenomenological kinetic coefficient is
discussed, and the possible cause of the residual charges observed after pulse
switching is explained by the trapped charge dynamics at the FE-DE interface.
The physical interpretation presented in this work can provide important
insights into the NC effect in MFIM capacitors and future studies of low-power
logic devices.
