Grain tailoring enables robust high-temperature ferroelectricity in ultrathin HZO films

Caption

Large, well-oriented grains enable ultrathin grain-tailored HZO (GT-HZO) to achieve strong ferroelectric polarization without electrical “wake-up” cycling. The optimized films also remain highly reliable at elevated temperatures, surviving more than 108 switching cycles and retaining stored information for at least 1000 hours at 225 °C.
