“Background Fabrication of self-organized nano-structures over solid surfaces using energetic ion beam irradiation has received a remarkable attention in the last couple of decades. It is an elegant and cost-effective single-step approach over lithographic methods for device fabrication. In general, a uniform ion irradiation of solid surfaces for intermediate energies (102 to 104 eV) causes a self-organized topographic pattern of ripples, holes, or dots [1–4]. On the other hand, irradiation with higher energies (106 to 108eV) causes the phase transformations [5].
