Technology#07 in February 2026 EditionCMOS-compatible ferroelectric field-effect transistors with 10-year data retention for non-volatile memories
Daniel Kraemer, Sunita Rao, Philip Montgomery et al.
OPENSTEM EDITORIAL SUMMARY
What the research examines
Engineers fabricate ferroelectric hafnium-zirconium oxide (HZO) field-effect transistors using atomic layer deposition with a high-k interlayer, demonstrating a 2.5 V memory window and extrapolated 10-year non-volatile retention at 85 °C.
Why it may matter
Overcomes write endurance and retention bottlenecks for ultra-dense, low-power embedded non-volatile memory.
What to examine carefully
Wake-up and fatigue effects caused by oxygen vacancy redistribution during the first 10^5 switching cycles require initialization pulses.
Editorial scope: This is a concise, independently written introduction based on the publisher information, not a full systematic review or independent replication. It must not replace reading the original methods, limitations and conclusions.

Questions to investigate
- What crystallization annealing temperature was required to stabilize the orthorhombic ferroelectric crystal phase?
- How was depolarization field-induced charge leakage mitigated at the semiconductor-oxide interface?
These are independently proposed educational investigations, not activities that the original research authors claim to have completed.
