Abstract
The thermal-field (TF) treatment conditions for <111> oriented single-crystal tungsten tips were systematically studied using the remolding technique, which uses the reversely polarized field in the treatment opposite to the field emission polarity. A treatment sequence has been established for producing nanotips that end with a very sharp <111> apex at the end.
