On the persistence of polar domains in ultrathin ferroelectric capacitors
On the persistence of polar domains in ultrathin ferroelectric capacitors
The instability of ferroelectric ordering in ultra-thin films is one of the most important fundamental issues pertaining realization of a number of electronic devices with enhanced functionality, such as ferroelectric and multiferroic tunnel junctions or ferroelectric field effect transistors. In this paper, we investigate the polarization state of archetypal ultrathin …
