CG: the geometry optimizing AFM image simulator |
CG-RISM: the AFM simulator for atomic scale in liquid environment |
If you want to perform simulations in vacuum environment, please use the CG.
By contrast,
if you want to perform simulations in liquid environment, please use the CG-RISM.
Advantages of the CG and the CG-RISM are as follows: |
Estimating the molecular configuration that is stabel with respect to the total energy,
the CG and the CG-RISM optimize the structure of molecules and obtain their AFM image.
|
The CG and the CG-RISM provide frequency shift images of the non-contact AFM under molecular scale in vacuum and liquid environment.
|
The CG and the CG-RISM can calculate
the energy curve representing the variation of the potential energy
and
the force curve (the force-distance plot)
for the system consisting of the tip and the sample.
|
The CG and the CG-RISM can simulate non-contact AFM images
with the following two modes:
(1)
the constant height mode where the height of the tip is fixed
and
(2)
the constant force mode where the force that the tip feels is fixed.
