The exotic topological domains in ferroelectrics and multiferroics have attracted extensive interest recent years due to their novel functionalities potential applications nanoelectronic devices. One of the key challenges for such is a realization robust yet reversibly switchable nanoscale domain states with high density, wherein spontaneous structures can be individually addressed controlled. This has been accomplished our work using density arrays epitaxial BiFeO3 (BFO) nanodots lateral...
Abstract Ultrahigh density well-registered oxide nanocapacitors are very essential for large scale integrated microelectronic devices. We report the fabrication of well-ordered multiferroic BiFeO 3 nanocapacitor arrays by a combination pulsed laser deposition (PLD) method and anodic aluminum (AAO) template method. The capacitor cells consist /SrRuO (BFO/SRO) heterostructural nanodots on conductive Nb-doped SrTiO (Nb-STO) substrates with lateral size ~60 nm. These capacitors also show...
Ferroelectric resistive switching (RS), manifested as a switchable ferroelectric diode effect, was observed in well-ordered and high-density nanocapacitor arrays based on continuous BiFeO3 (BFO) ultrathin films isolated Pt nanonelectrodes. The thickness of BFO the lateral dimension electrodes were aggressively scaled down to <10 nm ∼60 nm, respectively, representing an ultrahigh memory density ∼100 Gbit/inch2. Moreover, RS behavior those nanocapacitors showed large ON/OFF ratio (above 103)...
Efficient and cost-competitive fabrication of high-quality ferroelectric multiferroic nanostructures is general interest. In this work, a top-down nano-patterning technique developed by the Ar+ ion beam etching in combination with sacrificed ultrathin anodic alumina (AAO) mask. This demonstrated preparation epitaxial BiFeO3 (BFO) various geometries, including nanodot anti-nanodot arrays. The lateral dot size as small ∼60 nm an ultrahigh density Gbit/inch2 achieved. It revealed that process...
We investigate the resistive switching and ferroelectric polarization properties of high-quality epitaxial BiFeO3 thin films in various temperature ranges. The room current–voltage (I–V) curve exhibits a well-established polarization-modulated memristor behavior. At low temperatures (< 253 K), I–V shows an open circuit voltage (OCV), which possibly originates from dielectric relaxation effects, accompanied with current hump due to reversal displacement current. While at relative higher (>...
In this work, self-assembled ferroelectric BiFeO3 (BFO) and Pb(Zr,Ti)O3 (PZT) nanocapacitors were fabricated by a one-step pulsed-laser deposition process. Each individual nanocapacitor consists of SrRuO3 or LaSrMnO3 bottom electrode layer, an epitaxial middle layer nanoisland conductive Bi2O3 PbO2 as the top nanoelectrode. The nanoelectrodes have lateral size 10–100 nm depending on various equivalent thickness. as-fabricated exhibit unique so-called anti-domain structures, with opposite...
Azodye-doped TiO(2)/ormosil hybrid materials for photonic applications were prepared by a low temperature sol-gel process from an organic-inorganic system. Acid-catalyzed solutions of gamma-glycidoxypropyltrimethoxysilane and methyltrimethoxysilane mixed with tetrapropyl orthotitanate used as matrix precursors. The trans-cis-trans photoisomerization azobenzene small molecules in matrices was induced photoirradiation UV light subsequent visible light. It found that the film doped azodyes...
Developing effective methods to detect contamination in milk during production, processing, and storage is quite important but challenging. Difloxacin (DIF), due its great potential veterinary medicine for the treatment of bacterial infections, one most common organic contaminants milk, posing a significant threat human health. However, there lack high-performance means in-situ monitoring DIF. Herein, we have successfully achieved high-sensitivity high-selectivity fluorescence detection DIF...
Arrays of micro-sized LEDs which can be used as microdisplays have been demonstrated in recent years. In order to reduce the input and output connections arrays, we employ a matrix addressable architecture, all pixels each row are connected by common metal line on top window layer (top electrode) or at base substrate(bottom electrode). Decreasing size electrodes makes for minimizing device. The optic electronic isolation good ohmic contact also helpful obtain superior optical electrical...
