We investigated Al2O3 atomic layer deposition growth layer for encapsulation of organic light emitting diodes (OLEDs). It was found that surface properties of these O3-based Al2O3 were superior to those of H2O based Al2O3 grown at relative higher temperatures. Therefore, the water vapor transmission rate of ∼60 nm thick Al2O3 films can be reduced from × 10–4 g/(m2 day) (80 °C–H2O Cited by:

Tribostimulated exo-emission provides a sensitive technique to study anodically grown films on aluminum. As the substrate is deformed, electrons and other particles are emitted.
This emission is intimately related to the cracking of the oxide : David B. Snyder. Introduction. Aluminum oxide thin films are known to have desirable electrical characteristics for a variety of applications such as passivation, gas sensors, perovskite solar cells, organic field-effect transistors, organic light emitting diode (OLED) encapsulation, oxide gate dielectric in thin films transistors (TFT), transparent thin films transistors (TTFT), flexible thin.
SCHOTTKY EMISSION THROUGH THIN ALUMINUM -OXIDE FILMS INTRODUCTION During the past two years considerable interest has developed in the studies of electronic phenomena in metals and insulators and in current transfer processes where electrons pass through thin layers of insulating material by one or more of several the work in this area is in its early stages and the theo.

Instead of using water or other compounds for an oxygen source, oxygen is obtained from a metal alkoxide, which serves as both an oxygen and a metal source when it reacts with another metal compound such as a metal chloride or a metal alkyl. These reactions generally enable deposition of Tribostimulated emission from dense aluminum oxide thin films book of many metals.

Because of the chemical similarity between Al and Ga, the film growth onto GaAs facets can be easily achieved. However, it is quite difficult to fabricate Al2O3 films on Si wafers.

Anew sol-gel route has been applied to synthetize dense Al 2 O 3 thin films from aluminum isopropoxide (Al(OPri) 3)as raw precursor material.

Fig. 3 contains a transmission electron micrograph of an amorphous aluminum oxide film deposited on Si(1 0 0), in which the substrate temperature during aluminum oxide deposition was maintained at °C. A ∼1 nm thick SiO 2 interfacial layer was observed between the aluminum oxide film and the Si(1 0 0) substrate.
