Homogeneous growth of self-assembled Si nanopillar array via an asymmetric overlap of a spot beam laser

Nanosecond ultraviolet (UV) laser irradiation of Si thin films with a Gaussian beam was employed to study the transition from laser-induced periodic surface structures (LIPSS) to nanopillar formation. Single-pulse irradiation produced concentric modification regimes, ranging from...
