摘要：

Tungsten tips obtained through electrochemical etching have been characterized by scanning electron microscopy, scanning Auger microscopy, and scanning tunneling microscopy. While such tips resulted to be very sharp, a thick oxide layer (approximately 10 nm) is present at the apex. High-vacuum annealing at 1800 K removes most of such oxide.
