Inorganic Oxide Core, Polymer Shell Nanocomposite as a High K Gate Dielectric for Flexible Electronics Applications

Abstract

Organic/inorganic core shell nanoparticles have been synthesized using high K TiO(2) as the core nanoparticle, and polystyrene as the shell. This material is easy to process and forms transparent continuous thin films, which exhibit a dielectric constant enhancement of over 3 times that of bulk polystyrene. This new dielectric material has been incorporated into capacitors and thin film transistors (TFTs). Mobilities approaching 0.2 cm(2)/V.s have been measured for pentacene TFTs incorporating the new TiO(2) polystyrene nanostructured gate dielectric, indicating good surface properties for pentacene film growth. This novel strategy for generating high K flexible gate dielectrics will be of value in improving organic and flexible electronic device performance.

New materials and advances in making electronic skin for interactive robots

“…Other materials that have been investigated as dielectric material for flexible electronics applications include polymer composites comprising of nanofillers, high-K dielectric materials and liquid ion gels. [38] Some of the high-K nanomaterials used to develop hybrid dielectric materials includes TiO2 [39] and BaTiO3. [40] In addition to other high-K dielectric composite, high-K materials like aluminium oxide (Al2O3), [32] tantalum oxide (Ta2O5)/SiO2 [41] have also been used as gate dielectric.…”

Polyarylene Ether Nitrile-Based High-k Composites for Dielectric Applications

“…Unfortunately, the loss tangent of the system increases simultaneously due to the incompatibility between the organic substrate and the inorganic additives. As a result, the micromorphology of fillers, the distribution mode of the additives in the polymeric substrate, surface treatment, and preparation methods of the fillers (i.e., "core-shell" nanoarchitectures) [43][44][45][46] are equal important as the kind of fillers that determines the properties of the obtained composites [47][48][49][50][51]. This article reviews the progress of PEN-based composites exhibiting high-k for electric applications.…”

Computational Cogitation of Cn@Al12 Clusters

“…[17][18][19] Fast forward to the present day and one can find an evergrowing body of literature detailing the design and application of a vast array of hybrid nanoclusters in fields as diverse as biomedicine, [20][21][22][23][24][25][26][27] catalysis [28][29][30][31][32][33][34][35][36][37] and electronics. [38][39][40][41][42] Of most relevance to the results presented herein are the studies of core-shell systems comprising small cores ( 5 atoms) and relatively small shells ( 20 atoms), [2,10,[43][44][45][46][47][48][49][50][51][52] particularly those detailing the behaviour of doped Al 12 .…”
