A C70 close-packed surface was formed by a heating of the Si surface, which is covered with C70 molecules. The close-packed surface is assigned to high-temperature hexagonal close-packed phase. The stability of C70 close-packed surface and formation of nanometer scale structures are studied by the application of local electric field to the close-packed surface. An application of local electric field from scanning tunneling microscope tip to the C70 close-packed surface caused molecular scale evaporation. The application of local electric field near strain in the surface produced a very large void by an evaporation of more than 20 of C70 molecules.
