Abstract

The cryogenic switching behavior of 10 nm Hf 0.5 Zr 0.5 O 2 (HZO) capacitors is investigated down to −180 °C. A significant reduction in remanent polarization (2 P r ) and suppression of the wake-up effect are observed as the measurement temperature is lowered. Systematic field-dependent measurements reveal that increasing the readout and/or wake-up voltage leads to a comparable 2 P r at cryogenic temperatures, indicating that the degradation arises from incomplete field-induced switching rather than intrinsic material instability. These results confirm that ferroelectric performance of HZO persists under cryogenic conditions, as long as sufficient electric fields are applied. The study offers practical insights into the design of cryogenic-compatible ferroelectric memory applications.
