| Polyvinyl formal (PVF) of organic film deposition of metal films XPS
Rooms, etc.), evaporation heater is not installed the metal evaporation source of heat radiation of PvF membrane. PVF film measured by XPS before and after irradiation ch peaks, and the results shown in Figure 6. Figure 6 shows the peak position, peak shape and no change in intensity, indicating that irradiation did not cause PVF film Ch peak heat of three valence changes in the relative content of PVF film deposition Au, Pd, Ag, the interface of the three cl species relative content of valence change facts show that the three metal atoms are deposited in the PvF chemical adsorption membrane. 4 Conclusion (1) This method can be prepared PvF membrane to maintain its purity of line with experiments. (2) ultra-high vacuum conditions, using resistance heating evaporation in the PVF film based on the Au, Pd and Ag, in the film process, / ev Figure 6PVF film heat radiation peaks around the cl Fig. Heavy brow 6ClspeaksofPVFfilmbeforeandafterheatingirradiation ∞ q q 0 = head shut the three summer-ulI】 ● H j-222 Vacuum Science and Technology, Volume 16 is not mixed with other ingredients found around or play a role. (3) PVF film based on the deposited Au, Pd, Ag, the interface of the three valence changes in the relative content of Cls, the three metal atoms in the PVF film deposition is a chemical adsorption of the work to get the XPS test Bao Shining Professor and Professor Zhen-Guo Ji cut help, thank the people crossing the reference field,ugg boots günstig, the assassination of German glory.
