Mahmood AS, Venkatakrishnan K, Tan B - Nanoscale Res Lett (2013)

Bottom Line: This article presents 3-D aluminum micro-nanostructures for enhanced light absorption.These micro-nanostructures showed enhanced light absorption, which is attributed to surface plasmonics induced by the generation of both nano- and microstructures.These micro-nanostructures may be promising for solar cell applications.

ABSTRACT
This article presents 3-D aluminum micro-nanostructures for enhanced light absorption. Periodic microhole arrays were created by firing a train of femtosecond laser pulses at megahertz pulse frequency onto the surface of an aluminum target at ambient conditions. The laser trains ablated the target surface and created microholes leading to the generation of deposited nanostructures inside and around the microholes. These micro-nanostructures showed enhanced light absorption, which is attributed to surface plasmonics induced by the generation of both nano- and microstructures. These micro-nanostructures may be promising for solar cell applications.
