Engineering Wake-Up-Free Ferroelectric Capacitors with Enhanced High-Temperature Reliability
Nashrah Afroze, Salma Soliman, Yu-Hsin Kuo +5
We systematically explore the design space of ferroelectric hafnium-zirconium oxide (H0.5Z0.5O or HZO) heterostructures for reliable high temperature operation. HZO films are depos…
Sub-nm2 ferroelectric domains via charged 180 degree walls in ZrO2
Nashrah Afroze, Hamoon Fahrvandi, Guodong Ren +31
Flat phonon bands in fluorite ferroelectrics (HfO2 or ZrO2) shrink polar domains laterally to an irreducible half-unit-cell width (0.27 nm) within which the vertical arrangement of…
The First Switch Effect in Ferroelectric Field-Effect Transistors
Priyankka Ravikumar, Prasanna Venkatesan, Chinsung Park +7
In this work, a ferroelectric field-effect transistor (FEFET) is systematically characterized and compared with an equivalent standard MOSFET with an equivalent oxide thickness. We…
ALD-Derived WO3-x Leads to Nearly Wake-Up-Free Ferroelectric Hf0.5Zr0.5O2 at Elevated Temperatures
Nashrah Afroze, Jihoon Choi, Salma Soliman +10
Breaking the memory wall in advanced computing architectures will require complex 3D integration of emerging memory materials such as ferroelectrics-either within the back-end-of-l…
Hf/Zr Superlattice-Based High-\k{appa} Gate Dielectrics with Dipole Layer Engineering for Advanced CMOS
Taeyoung Song, Sanghyun Kang, Yu Hsin Kuo +7
Advanced logic transistors require gate dielectrics that achieve sub-nanometer equivalent oxide thickness (EOT), suppress leakage, and satisfy three key requirements: (i) compatibi…
FeNOMS: Enhancing Open Modification Spectral Library Search with In-Storage Processing on Ferroelectric NAND (FeNAND) Flash
Sumukh Pinge, Ashkan Moradifirouzabadi, Keming Fan +29
The rapid expansion of mass spectrometry (MS) data, now exceeding hundreds of terabytes, poses significant challenges for efficient, large-scale library search - a critical compone…
