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…
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…
