Atomic force microscopy imaging of ZnO nanodots deposited on quartz by sparking off different tip shapes

Atomic force microscopy imaging of ZnO nanodots deposited on quartz by sparking off different tip shapes

We have demonstrated a simple method for depositing ZnO nanodots on quartz substrates by sparking off different tip shapes at voltages of 2, 4 and 6 kV in air at atmospheric pressure. A comparison was made among the three tip shapes: the sharp tip, the conical tip and the dull tip. The surface morph...
