LDOS (STM)

LDOS (block-type)

Local Density-Of-States information. This can be used to generate STM images in the Tersoff-Hamann approximation [35].

LDOS
  { Shift eshift }
  { DeltaNeg deneg }
  { DeltaPos depos }
End

Shift: The energy bias with respect to the fermi level in a.u.. Default = 0.0

DeltaNeg Default = 1e-4 a.u.

DeltaPos Default = 1e-4

The local density of states is integrated over the interval eshift-deneg through eshift+depos.
Example of an LDOS restart:

...
Restart my.runkf &
 DensityPlot
End

Grid
Type Coarse
End

DensityPlot
LDOS_scf
End

LDOS
 Shift      0.1
 DeltaNeg .001
 DeltaPos 0
End 

According to this example, we restart from the result file of a previous calculation. The calculation will generate a file TAPE41 which can be viewed with adfview. (Rename the file to my.t41)
