[Abstract]:This paper is composed of the following two parts:
Organic metal composite film used as optical storage medium
A new organic metal composite film structure, which can be used as light storage medium, is found. The film consists of organic molecular layer and nano scale Ag metal layer. The process of making the composite film is discussed. There are no A1 reflector, Ag gold layer thickness, laser power and time for different organic molecules in the structure. The effect of the composite film is preliminarily studied.
The laser writing point was characterized by SEM morphology, and the microstructural changes were found in the irradiated region. The Ag metal layer was studied by the ultraviolet visible (Uv-vis) absorption spectrum and the X ray photoelectron spectroscopy (XPS). It was found that when the thickness was less than 10nm, the Ag gold layer existed in the form of nanoparticles and was absorbed through Uv-vis absorption. The interaction between the metal layer and the organic layer is found by the spectrum. It is believed that the interaction leads to the formation of the laser writing point.
It is considered that the structure of organic metal composite film has potential as an optical storage medium, and has a good reference value for future research.
Preparation of CuSCN granular materials by solid-liquid interfacial reaction and electrical storage devices based on the material
A new alcohol solution system was used to prepare CuSCN granular film. A film composed of a specific shape of CuSCN particles was prepared by the solid to liquid interface reaction between Cu film and KSCN alcohol solution. It was found that the shape of the generated CuSCN particles could be controlled by changing the type of solvent and the temperature of the solid liquid interface reaction. When the reaction temperature is controlled at 20 C, homogeneous CuSCN round micron sized particles can be obtained.
An electrical storage device based on the above CuSCN film is prepared. The Cu and Al electrodes are fabricated on two sides of the CuSCN film medium layer. The electrical storage devices that can be written in multiple reads (WORM) are obtained. The electrical properties of the prepared electrical storage devices, such as the yield, the state ratio, the threshold distribution and so on, are studied. The Cu thinning of the reaction is adjusted. The thickness of the film can be used to obtain an electrical storage device with high yield and narrow threshold distribution.
