Nowadays, with more and more functions of electronic products, an electronic product usually consists of thousands of electronic components, and the reliability of an electronic product is not only determined by the inherent reliability of each component, but is also closely related to the assembly technologies of these components. Soldering is an important process in electronics assembly technologies,...
A new synthetic method of Ag-Fe2O3 core-shell composite nanoparticles is reported. The silver nanoparticles used as the seeds was synthesised by an in situ method in the presence of p-toluenesulfonic acid-doped polyaniline. Then the Fe2O3 was coated on the surface of silver nanoparticles in the dimethylformamide solution. The core-shell structure of Ag-Fe2O3 composite nanoparticles was confirmed by...
One-dimensional silver nanorods and nanodisks have been successfully synthesised through a facile method of the polymer template-assisted synthesis. The sample was characterised by a variety of techniques, such as transmission electron microscopy (TEM), scan electron microscopy (SEM) and a UV-vis spectrometer. The as-obtained nanorods and nanodisks are single crystalline with an average size of about...
The fabrication and properties of CdTe layer are most important to the performance of CdTe thin film solar cells, among their several function layers. In the paper, a technology of closed-space sublimation(CSS) in Ar+O2 atmosphere has been studied and a method of depositing CdTe thin films on smooth glass substrate has been developed. The structural properties of these films deposited in an appropriate...
