Morphotropic Phase Boundary (MPB) Induced Enhancement of Ferroelectric and Piezoelectric Properties in Li and Ta modified K0.5Na0.5NbO3
Satyaranjan Sahoo, Dhiren K. Pradhan, Shalini Kumari +9
Lead-free (K0.48Na0.48Li0.04)(Nb1-xTax)O3 (KNLNT-x) ceramics were synthesized to study the effects of Li and Ta substitution on phase transition behavior, microstructure, and ferro…
Kilobyte-Scale, Selector-Free, Temperature-Hard AlScN Ferroelectric Diode Crossbar Arrays
Zirun Han, Chao-Chuan Chen, Dhiren K. Pradhan +12
We report the fabrication and characterization of kilobyte-scale, selector-free, ferroelectric (FE) diode crossbar memory arrays based on aluminum scandium nitride (AlScN). Utilizi…
Multi-State, Ultra-thin, BEOL-Compatible AlScN Ferroelectric Diodes
Kwan-Ho Kim, Zirun Han, Yinuo Zhang +6
The growth in data generation necessitates efficient data processing technologies to address the von Neumann bottleneck in conventional computer architecture. Memory-driven computi…
Scalable and Stable Ferroelectric Non-Volatile Memory at > 500 C
Dhiren K. Pradhan, David C. Moore, Gwangwoo Kim +12
Non-volatile memory (NVM) devices that reliably operate at temperatures above 300 C are currently non-existent and remains a critically unmet challenge in the development o…
