TL;DR: A simple solution method is used to prepare emissive hybrid quantum dots consisting of a ZnO core wrapped in a shell of single-layer graphene to make a white-light-emitting diode, and two additional blue emission peaks are observed in the luminescent spectrum of the quantum dot.

TL;DR: Noise reduction due to the Al2O3 passivation was expressed in terms of the reduced interface trap density values D(it) and N(it), extracted from the subthreshold slope (SS) and the CNF model, respectively.

TL;DR: The electrical properties of flexible nonvolatile organic bistable devices fabricated with graphene sandwiched between two insulating poly(methyl methacrylate) (PMMA) polymer layers were investigated and current-voltage measurements showed a current bistability due to the existence of the graphene, indicative of charge storage in the graphene.

TL;DR: In this paper, the X-ray diffraction (XRD) θ-rocking curve of undoped ZnO thin films was shown to have the narrowest full width half maximum (FWHM) with a minimum channeling yield of 4% to 5%.

TL;DR: This study presents an alternative QD patterning technique using conventional photolithography combined with charge-assisted layer-by-layer (LbL) assembly to solve the trade-offs of the traditional patterning processes and believes that this process provides a solution to achieving both high-resolution and large-scale QDpattern applicable to not only display, but also to practical photonic device research and development.
