2.1. Film preparation
Pure ZnO thin films were prepared on the glass substrate using RF magnetron sputtering system. And Mg, Ga doped (3 wt%) ZnO thin films were prepared on the ZnO pre-sputtered glass substrate using RF magnetron sputtering system. The PureZnO target was made from high purity ZnO powder (99.99 %) . The MZO/GZO targets were made from high purity ZnO powder (
2. Experimental
The films were deposited in a conventional horizontal furnace on Si(1 1 1) substrates. SnO2 (99.99%) (Mol10:2) and ZnO/Ge slices (99.999%, purity), (Mol 10:2) powders were used as the source materials for growth of the Sn- and Ge-doped ZnO films, respectively. The ZnO/SnO2 powder was placed on an alumina boat and inserted into a horizontal tube furnace, in order to serve as th
conductivity measurements. The results show that the Au parti- cles are well-protected by the dithiol linker molecules and do not fuse into larger un- ited. The thin film material obtained clearly exhibits nonmetallic properties(i.e., electro -hopping conductivity and optical constants very different from those of metals).
Experimental
Preparation of gold seed solution
film of oil, glycerin or water is generally used between the transducer and the test surface.
When scanning over the part or making precise measurements, an immersion technique is often used. In immersionultrasonic testing both the transducer and the part are immersed in the couplant, which is typically water. This method of coupling makes it easier to maintain consistent coupling while moving a
3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.
