Article Synopsis
- Isolated pyramids ranging from 30-80 nm in width and 3-20 nm in height form on the Ge (110) surface during sputter-annealing cycles, characterized by {19 13 1} faceting and a steep mound at their top.
- The pyramids are observed between 200 eV and 400 eV ion energies, and their formation is enhanced by the presence of silver (Ag), suggesting that Ag co-sputtering triggers their growth.
- Above 400 eV, surface damage occurs, preventing pyramid formation, particularly due to inadequate annealing processes.
