  2. A New Perspective of Capacitive-Inductive Transition in Ferroelectrics

    24 Jan 2023 | | Contributor(s):: deepalakshmi chandrasekaran

    Ferroelectrics are like ferromagnetics in that the different areas of ferroelectrics get polarized in different directions based on the charge density and finally the net charge of the material, as a whole gives the resultant polarization in a particular direction. The negative permittivity...

  3. CMOS+X: Integrated Ferroelectric Devices for Energy Efficient Electronics

    09 Dec 2022 | | Contributor(s):: Sayeef Salahuddin

    In this talk, I shall briefly present how integrated ferroelectric devices offer a new pathway in this context. First, I shall discuss the phenomenon of negative capacitance in ferroelectric materials. A fundamentally new state in the ferroelectrics, negative capacitance promises to reduce...

  4. Underlying Physics Behind Negative Capacitance

    30 Nov 2022 |

    As explained in the Nature article, the fundamental understanding of negative capacitance is not fully complete. Ferroelectrics are like ferromagnetics in that the different areas of the ferroelectrics get polarized in different directions based on the charge density and finally, the net charge...

  6. IWCN 2021: Quantum Transport Simulation on 2D Ferroelectric Tunnel Junctions

    15 Jul 2021 | | Contributor(s):: Eunyeong Yang, Jiwon Chang

    In this work, we consider a simple asymmetric structure of metal-ferroelectric-metal (MFM) FTJs with two different ferroelectric materials, Hf0.5Zr0.5O2(HZO) and CuInP2S6(CIPS), respectively. To investigate the performance of FTJs theoretically, we first explore complex band structures of HZO...

  7. A Circuit-compatible SPICE Model for Phase-field Simulations of Multi-domain Ferroelectrics

    17 May 2021 | | Contributor(s):: Chia-Sheng Hsu, Sou-Chi Chang, Dmitri Nikonov, Ian Alexander Young, Azad Naeemi

    To describe the multi-domain FE switching dynamics, we present a circuit-compatible model that can solve the time-dependent Ginzburg-Landau (TDGL) equation and Poisson’s equation self-consistently in three-dimensional space with the SPICE simulator. In addition, the FE domain structures...

  8. Florida Ferroelectric Tunnel Junction Device Model

  9. Ferroelectric Domain Structure of La-modified Lead Titanate Ceramics

    14 Dec 2018 | | Contributor(s):: Brian Demczyk, G. Thomas

    Presentation describes the ferroelectric domain structure of Lanthanum-modified lead titanate ceramics, as deduced by transmission electron microscopy, including the ferroelectric to paraelectric phase transformation. A significant result was the observation of a minimum grain size for...

  13. A Tutorial Introduction to Negative-­Capacitor Landau Transistors: Perspectives on the Road Ahead

    04 Dec 2015 | | Contributor(s):: Muhammad A. Alam

    In this talk, I use a simple graphical approach to demystify the device and explain why the experimental results are easy to misinterpret. Since the NC-FET is just a special case of a much broader class of phase-change devices and systems (e.g., transistors, memories, MEMS, logic-in-memory...
