Nonvolatile ferroelectric memory based on PbTiO3 gated single-layer MoS2 field-effect transistor
We fabricated ferroelectric non-volatile random access memory (FeRAM) based on a field effect transistor (FET) consisting of a monolayer MoS2 channel and a ferroelectric PbTiO3 (PTO) thin film of gate insulator. ...

Ferroelectric switching response of P(VDF-TrFE) nanodots with and without nanomolds
We investigated ferroelectric switching response of poly(vinylidene fluoride-ran-trifluoroethylene) (P(VDF-TrFE)) nanodots with and without nanomolds using piezoelectric force microscopy. Nanomolds with diameter ...

Strain effect on ferroelectric polarization of epitaxial LuFeO3 thin films
Epitaxial LuFeO3(LFO) thin films were deposited on La0.5Sr0.5MnO3(LSMO)/LaAlO3(LAO) substrates by pulsed laser deposition method. The LFO thin film with a thickness of 100 nm exhibited tetragonally strained stru...
