Part of the Springer Theses book series (Springer Theses)


In this work, we use low-boiling, low viscosity ethanol, and for the first time employ the high boiling point and high viscosity sucrose as liquid environment for femtosecond laser irradiation on silicon. The microcone and micromolar arrays were successfully prepared in ethanol and sucrose, respectively. It is indicated that the heights are tunable by simply controlling the laser pulse energy.
