Periodic Nanostructures and Optical Properties of InP Induced by Femtosecond Laser Pulses

摘要

In this letter, InP periodic nanostructures were synthesized by linearly polarised femtosecond laser. Perfect morphologies of InP nanostructures can be obtained under an appropriate laser power. Further, to restrain surface sates of InP, the Al_2O_3 layers were deposited on InP nanostructures by atomic layer deposition (ALD). The optical properties of InP nanostructures were investigated by Raman and Photoluminescence (PL). And the transverse optical (TO) peak and novel luminescence emission can be observed due to the formation of the periodic nanostructures.
