Table 1 Summary of effects of laser conditions to tip growth
Laser parameters | Effects on nanotip growth |
|---|---|
Pulse width | Short pulses yield narrow long tips |
Repetition rate | Higher repetition rate promotes the growth of dense, oriented narrow nanotips |
Dwell time | Longer dwell time increases the population of nanotips. However, beyond an optimum dwell time, over heating will remelt the newly formed nanotips |
Polarization | Linear (p-) polarization increases the population of nanotips |
