Flexible ferroelectric element based on van der Waals heteroepitaxy
We present a promising technology for nonvolatile flexible electronic devices: A direct fabrication of epitaxial lead zirconium titanate (PZT) on flexible mica substrate via van der Waals epitaxy. These single-crystalline flexible ferroelectric PZT films not only retain their performance, reliability, and thermal stability comparable to those on rigid counterparts in tests of nonvolatile memory...
متن کاملExact Mixed Integer Programming for Integrated Scheduling and Process Planning in Flexible Environment
This paper presented a mixed integer programming for integrated scheduling and process planning. The presented process plan included some orders with precedence relations similar to Multiple Traveling Salesman Problem (MTSP), which was categorized as an NP-hard problem. These types of problems are also called advanced planning because of simultaneously determining the appropriate sequence and m...
متن کاملJunctionless ferroelectric field effect transistors based on ultrathin silicon nanomembranes
The paper reported the fabrication and operation of nonvolatile ferroelectric field effect transistors (FeFETs) with a top gate and top contact structure. Ultrathin Si nanomembranes without source and drain doping were used as the semiconducting layers whose electrical performance was modulated by the polarization of the ferroelectric poly(vinylidene fluoride trifluoroethylene) [P(VDF-TrFE)] th...

Keywords: HfO 2 Analytical model Surface potential Ferroelectric Nonvolatile memory Fe-TFET a b s t r a c t The implementation and operation of the nonvolatile ferroelectric memory (NVM) tunnel field effect transistors with silicon-doped HfO 2 is proposed and theoretically examined for the first time, showing that ferroelectric nonvolatile tunnel field effect transistor (Fe-TFET) can operate as...
متن کاملCharacterization of Bi and Fe co-doped PZT capacitors for FeRAM.
Ferroelectric random access memory (FeRAM) has been in mass production for over 15 years. Higher polarization ferroelectric materials are needed for future devices which can operate above about 100 °C. With this goal in mind, co-doping of thin Pb(Zr40,Ti60)O3 (PZT) films with 1 at.% Bi and 1 at.% Fe was examined in order to enhance the ferroelectric properties as well as characterize the doped ...
