Physical Vapor Deposition Results

  • Figure1
This picture shows the observation results of the 40 micron polystyrene beads.


  • Figure2
This picture shows the observation results of 40 micron polystyrene beads with completely covered by gold.


  • Figure3
This picture shows the observation results of the 40 micron silica beads with half vapor deposition of gold.


  • Figure4
This picture shows the observation result of 40 micron polystyrene beads with half vapor deposition of gold.


  • Discussion
From these pictures, we observed that PVD can make hemisphere membrane of gold. By comparing the color of figure1 and figure2, micro-beads completely covered by gold are more black and have a metallic luster.  From figure3 , it is possible that the size of 40μm beads can deposit gold as hemisphere in that the colors of beads sphere’s limbs are different .Figure 4 shows that 10 micron sized beads can also deposit gold as hemisphere, because metallic luster color and white color are dotted in one sphere.
