Abstract: At 700℃, ZnO nanostructures with tetrapodlike and wire-like morphologies were synthesized using thermal evaporation method. Different source materials were used and the ambient gas was adjusted to study their influences on ZnO products. Field-emission measurements were applied to compare the field-emission characteristics of the two different morphologies of ZnO nanostructures.

Key words: thermal evaporation, field-emission, ZnO nanostructures, thermal evaporation, field-emission
