Fabrication of Mo pyramidal-shape single atom tips covered by a noble metal

- Provide another option for a material to produce single atom tips.
- Selecting an oxide that is easier to remove from the surface of the metal is important in the manufacture of single-atom tips.
- The single atom tips will have a self-assembled formation after annealing the Mo tips covered by noble metal.
- There are two types of pyramidal structures formed on Mo (1 1 1) facets.
