Breakdown-limited endurance in HZO FeFETs: mechanism and improvement under bipolar stress
Kasidit Toprasertpong, Mitsuru Takenaka, Shinichi Takagi
Breakdown is one of main failure mechanisms that limit write endurance of ferroelectric devices using hafnium oxide-based ferroelectric materials. In this study, we investigate the…
