Intrinsic defects in CdTe and CdZnTe alloys

Nava Setter, Alexander Tagantsev, Alexandra Sarabando de Carvalho

The Cd vacancy (VCd) and Te anti-site (TeCd) are two dominant defects in CdTe and CdZnTe alloys grown in Te-rich conditions. We examine the properties of these two intrinsic defects in Cd1-xZnxTe alloys with x

Large-scale fabrication of titanium-rich perovskite PZT submicro/nano wires and their electromechanical properties

Nava Setter, Silviu Cosmin Sandu, Jian Wang

We report a 2-step approach to prepare tetragonal perovskite PbZr0.1Ti0.9O3 submicro/nano wires in gram scale and with over 95% wire content. Non-perovskite precursor wires were first fabricated by hydrothermal processing. A subsequent annealing in a PbO a ...

HREM studies of twins in Cd1−xZnxTe (x ≈ 0.04) thin films grown by molecular beam epitaxy

Nava Setter, Igor Stolichnov, Marco Cantoni

The microstructure of ferroelectric Cd1−xZnxTe (CZT) thin films with x ≈ 0.04 grown by molecular beam epitaxy has been studied by means of cross sectional high-resolution transmission electron microscopy (HREM). High- density {1 1 1} lamellar twins are fou ...

1T Memory Cell Based on PVDF-TrFE Field Effect Transistor

Didier Bouvet, Nava Setter, Igor Stolichnov, Mihai Adrian Ionescu, Roman Gysel, Giovanni Antonio Salvatore, Sebastian Riester

Interest in PVDF-TrFE copolymers as ferroelectric material for Memory application is driven by the prospect of having low cost, low operating voltage and fully organic device. Some previous studies reported FET designs using copolymers [refs 1,2] but none ...

Low voltage Ferroelectric FET with sub-100nm copolymer P(VDF-TrFE) gate dielectric for non-volatile 1T memory

Didier Bouvet, Nava Setter, Igor Stolichnov, Mihai Adrian Ionescu, Giovanni Antonio Salvatore

A polymer based Ferroelectric gate FET at 1T non-volatile memory on bulk silicon is demonstrated. Spin-coated 40 nm and 100 nm P(VDF-TrFE) (70%-30%) ultra-thin films have been integrated onto 10 nm SiO₂ layer as gate dielectric into a conventional silicon ...

Electrical tuning of dc bias induced acoustic resonances in paraelectric thin films

Nava Setter, Alexander Tagantsev, Andreas Nöth

A theoretical model for the dc bias dependence of induced acoustic resonances in paraelectric materials is presented. The field dependent piezoelectric constitutive equations were derived from the Landau free energy expansion with respect to the ferroelect ...
