Plasma Sources and Feedback Control in Pretreatment Web
... intensity as shown in Figure 8, these processes can be kept constant. It is also critical that the process be controlled so that no excess metal is deposited on the web itself. This can lead to a reduction in target life and “seed” layers being deposited on the web surface. These seed layers can rea ...

... The above structural characterization results demonstrate that the ZnO nanostructures prepared via different synthetic routes have different exposed ratios of polar surfaces. The ZNWs and ZNSs are dominated by their nonpolar {1010̅ } planes, while the dominant surfaces for ZNDs are the (0001) polar pl ...

A corrugated surface is a metal slab, into which a series of vertical slots have been cut, as depicted in Fig. 4. The slots are narrow, so that many of them fit within one wavelength across the slab. ...
