TEM Pictures of STM Tips

TEM Picture of a cut STM Tip (Pt/Ir, 0.008" diameter). The image was taken before the STM experiment
200 kV, Bar length = 5 micrometer
The cut tip is not well-shaped and sometimes it produces multiple tips.
But it can be very sharp at the end.

TEM pictures were taken by Elton Graugnard and Takhee Lee (Sep. 1999).
