Thermal Processing Limits in Oxide-Channel Ferroelectric Field Effect Transistors
Lance Fernandes, Yu-Hsin Kuo, Chengyang Zhang +15
In this work, we report a systematic study of the impact of high-temperature post-capping thermal annealing on the memory characteristics of Oxide-semiconductor channel ferroelectr…
ALD Oxidant as A Tuning Knob for Memory Window Expansion in Ferroelectric FETs for Vertical NAND Applications
Ranie Jeyakumar, Prasanna Venkatesan, Lance Fernandes +12
Dielectric inserts are widely used to expand the memory window (MW) in ferroelectric FETs (FeFETs) for vertical NAND applications, with prior efforts focused primarily on material…
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…
Pulse-Mode Operation and Reliability of BEOL-Compatible Ferroelectric Non-Volatile Capacitive Memories with Amorphous Oxide Semiconductor Channels
Junmo Lee, Chengyang Zhang, Tae-Hyeon Kim +2
Non-volatile capacitive memories (nvCAPs) exhibiting AC small-signal capacitance on/off ratio (Con/Coff) with non-destructive read have emerged as a promising device for next-gener…
Revealing Phonon Bridge Effect for Amorphous vs Crystalline Metal-Silicide Layers at Si/Ti Interfaces by a Machine Learning Potential
Mayur Singh, Lokanath Patra, Chengyang Zhang +4
Metal-semiconductor interfaces play a central role in micro and nano-electronic devices as heat dissipation or temperature drop across these interfaces can significantly affect dev…
