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 (several nanometres) ferr...
متن کاملModeling of Structure Effect for Ferroelectric Capacitor Based on Poly(vinylidene fluoride-trifluoroethylene) Ultrathin Films
The characteristics of ferroelectric capacitors with poly(vinylidene fluoride-trifluoroethlene) (P(VDF-TrFE)) films have been studied at different structures of cell electrodes. It is suggested that the effect of electrode structures could induce changes of performance. Remarkably, cells with line electrodes display a better polarization and fatigue resistance than those with flat electrodes. F...
متن کاملPiezoresponse force microscopy studies of switching behavior of ferroelectric capacitors on a 100-ns time scale.
Piezoresponse force microscopy is a powerful technique for nm-scale studies but is usually limited by response time. In this Letter, we report the first direct studies of ferroelectric capacitor switching on a submicrosecond time scale. Simultaneous domain imaging and sub-mus transient current measurements establish a direct relationship between polarization P(t) and domain kinetics. Switching ...
متن کاملSurface structure of ultrathin copolymer films of ferroelectric vinylidene fluoride (70%) with trifluoroethylene (30%) on graphite
The structure and local structural distortions, through the polarization manipulation, of crystalline films of ferroelectric vinylidene fluoride (70%) with trifluoroethylene (30%) [P(VDF-TrFE)] copolymer on graphite were studied by scanning tunneling microscopy (STM). A quasispiral twist in CuC bonds with rotations about the polymer chain axis was observed by high-resolution STM, indicating a s...
متن کاملThree-dimensional high-resolution reconstruction of polarization in ferroelectric capacitors by piezoresponse force microscopy
A combination of vertical and lateral piezoresponse force microscopy ~VPFM and LPFM, respectively! has been used to map the out-of-plane and in-plane polarization distribution, respectively, of ~111!-oriented Pb(Zr,Ti)O3-based ~PZT! ferroelectric patterned and reactively-ion-etched capacitors. While VPFM and LPFM have previously been used to determine the orientation of the polarization vector ...
