Hybrid AC EL structures with thin protective ZnO film

High-mobility ambipolar ZnO-graphene hybrid thin film transistors

In order to combine advantages of ZnO thin film transistors (TFTs) with a high on-off ratio and graphene TFTs with extremely high carrier mobility, we present a facile methodology for fabricating ZnO thin film/graphene hybrid two-dimensional TFTs. Hybrid TFTs exhibited ambipolar behavior, an outstanding electron mobility of 329.7 ± 16.9 cm(2)/V·s, and a high on-off ratio of 10(5). The ambipolar...

Hybrid organic/quantum dot thin film structures and devices

Organic light emitting diodes have undergone rapid advancement over the course of the past decade. Similarly, quantum dot synthesis has progressed to the point that room temperature highly efficient photoluminescence can be realized. It is the purpose of this work to utilize the beneficial properties of these two material sets in a robust light emitting device. New deposition techniques are nec...

ZnO-based transparent thin-film transistors

Highly transparent ZnO-based thin-film transistors ~TFTs! are fabricated with optical transmission ~including substrate! of ;75% in the visible portion of the electromagnetic spectrum. Current– voltage measurements indicate n-channel, enhancement-mode TFT operation with excellent drain current saturation and a drain current on-to-off ratio of ;10. Threshold voltages and channel mobilities of de...

Preparation and proposed mechanism of ZnO Nanostructure Thin Film on Glass with Highest c-axis Orientation

In this paper, ZnO thin film is deposited on slide glass substrate using the sol-gel process. Presenting well-defined orientation of ZnO thin films Nanostructure were obtained by dip coating of zinc acetate dihydrate, monoethanolamine (MEA), de-ionized water and isopropanol alcohol. The annealed ZnO thin films were transparent ca 85-90% in visible range with an absorption edges at about 375 nm....
