[Wien] STM

[Peter Blaha]

STM simulations make only sense for a surface. You cannot make STM for a 
bulk ???

3ddens does not include tip vibrations, but is very fast and 
conveniently lets you choose the best hight above the surface to 
reproduce experimental images.

Be careful with the STM mode of lapw5 in cases with angles differing 
from 90 degrees !

STM simulations are always a bit of an art, because the quality of the 
experimental STM images changes a lot with group / time / ....
