C60                              C70

 

 

 

  1. Draw the Si(100)-(2X1) surface.

 

  1. Why did the author choose Si(100)-(2X1) as the surface for interaction?

 

 

  1. In the field of nanotechnology, heat resistance and superconductivity are some of the heavily studied properties.  What was the author’s goal for the interaction of C70 and C84 with silicon?

 

  1. In figure 5, observed signals of scattered C60, C70, and C84 were compared with C60 from SiO2.  The author indicated at very high surface temperatures the C60 molecule fragments to C58 and absorbed carbon on SiO2.  Why did the author not interact C70, and C84­ with SiO2?  If the author did interact C84­ with SiO2, would C84 fragments to C82­ and absorbs carbon on SiO2? Based on figure 2, what conclusion can be made?

 

  1. What conclusion can be made from figure 6?  About C84?
