Dataset: Reversible oxygen migration and phase transitions in hafnia-based ferroelectric devices
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Unconventional ferroelectricity, robust at reduced nanoscale sizes, exhibited by hafnia-based thin-films  presents  tremendous  opportunities  in  nanoelectronics.  However,  the  exact  nature  of polarization  switching  remains  controversial.  Here,  we  investigate  epitaxial  Hf0.5Zr0.5O2(HZO) capacitors,  interfaced  with  oxygen  conducting  metals  (La0.67Sr0.33MnO3,  LSMO)  as  electrodes, using  atomic  resolution  electron  microscopy  while in  situelectrical  biasing.  By  direct  oxygen imaging, we observe  reversible oxygen vacancy  migration from the bottom to the top electrode through HZO and reveal associated reversible structural phase transitions in the epitaxial LSMO and  HZO  layers.  We  follow  the  phase  transition  pathways  at  the  atomic  scale  and  identify  that these mechanisms are at play both in tunne' .
