Surface Modification on Solution Processable ZrO2 High-k Dielectrics for Low Voltage Operations of Organic Thin Film Transistors
High quality zirconium oxide (ZrO2) high-k dielectrics have been fabricated by chemical solution processes. The ZrO2 thin films annealed at various temperatures were studied from microstructure properties to electric properties in detail. The dielectric film annealed at 700 °C features a smooth surface, low leakage current density (1.89 × 10–6 A/cm2 @ ?3 MV/cm) and high dielectric constant...

Chemical cross-linked polyvinyl alcohol/cellulose nanocrystal composite films with high structural stability by spraying Fenton reagent as initiator
Cross-linked polyvinyl alcohol (PVA) composite films with high structural stability were prepared by free radical copolymerization between cellulose nanocrystal (CNC) and maleic anhydride (MAH) modified PVA through spraying Fenton free radical as initiator. The influence of chemical cross-linked and physical network structure on mechanical, thermal and water absorption properties of the composit...

158. Supertoughened Polylactide Binary Blend with High Heat Deflection Temperature Achieved by Thermal Annealing above the Glass Transition Temperature
Through thermal annealing above the glass transition temperature, a supertoughened binary blend with the highest notched Izod impact strength of 98 KJ/m2 was achieved, which was about 52 times of that of neat polylactide (PLA; 1.9 KJ/m2). The binary blend was composed of biocompatible and biodegradable PLA and ethylene?acrylic ester?glycidyl methacrylate terpolymer (EGMA) elastomer at the compos...

Solvent-induced textured structure and improved crystallinity for high performance perovskite solar cells
We demonstrate an environment-friendly solvent treatment that leads to a dramatic performance improvement of perovskite solar cells, with power conversion efficiency as high as 18%, with good stability. The solvent not only improves perovskite film morphology and crystallinity, but also, at proper growth conditions, leads to the formation of a self-induced textured structure on a dense layer; th...

High Mobility Amorphous Indium-Gallium-Zinc-Oxide Thin-Film Transistor by Aluminum Oxide Passivation Layer
This letter demonstrates a high mobility amorphous Indium-Gallium-Zinc Oxide (a-IGZO) thin-film transistor (TFT) with aluminum oxide (Al2O3) passivation layer by radio frequency (RF) magnetron sputtering and copper (Cu) source/drain electrodes. The fabricated a-IGZO TFT exhibited 20 times higher saturation mobility (142.0 cm^{2}/Vs) than the reference device without Al2O3 passivation layer. The ...

High-density array of ferroelectric nanodots with robust and reversibly switchable topological domain states
The exotic topological domains in ferroelectrics and multiferroics have attracted extensive interest in recent years due to their novel functionalities and potential applications in nanoelectronic devices. One of the key challenges for such applications is a realization of robust yet reversibly switchable nanoscale topological domain states with high density, wherein spontaneous topological stru...

High performance organic nonvolatile memory transistors based on HfO2 and poly(alpha-methylstyrene) electret hybrid charge-trapping layers
In this work, we fabricated a high performance flash-type organic nonvolatile memory transistor, which adopted polymer-electret poly(a-methylstyrene) (PaMS) and HfO2 films as hybrid charge trapping layer (CTL). Compared with a single HfO2 or PaMS CTL structure, the hybrid HfO2/PaMS CTL structure can provide enhanced charge trapping efficiency to increase the device operation speed and reduce the...

The flame retardant and smoke suppression effect of fullerene by trapping radicals in decabromodiphenyl oxide/Sb2O3 flame-retarded high density polyethylene
To improve the large release of smoke and heat for brominated flame retardants (BFRs) in fire hazard, fullerene (C60) had been introduced in high density polyethylene (HDPE)/bromine flame retardant (Deca/Sb2O3, BFR in short) system in this study. The effects of C60 on the thermal properties, flame retardant properties, rheological behaviors, and smoke release behaviors in HDPE/BFR blends were re...

High mobility solution-processed C8-BTBT organic thin-film transistors via UV-ozone interface modification
The interface between the dielectric and the active layer plays a critical role on the performance of solution-processed organic thin-film transistors (OTFTs). However, the creation of a high quality interface still represents a considerable challenge because it requires the balancing of surface energy with surface wettability. This study shows that UV-Ozone
treatment is very effective to obt...
