basic principle of two probe system

[Anders Blom]

I don't understand what is meant by "molecule mode", there is no such concept in VNL. You probable have a very clear idea what you want, but you need to explain it in more details, perhaps with a picture?

In ATK-VNL builder we have seen 3 modes i.e molecule mode, bulk mode and device mode. But device mode only show unit cell part. Is this unit cell part can be shown in molecule mode?? For more clarity I have attached a picture please find it.

Thanks!

Ok, that's kind of what I though. These are not "view" modes, the "molecule mode" here means that you actually transform the system to a molecule. This will, indeed, only take the central region.

But the same visual effect can be obtained in "device mode", as I mentioned above, by just selecting all 3 unit cells to be invisible in the Properties dialog.

Hi Dr. Blom,

As you told me to show the geometry in covalent:

"In the Viewer, right-click the 3D plot and choose Properties. Then you can set the atom size to covalent; you need to do it in each region (left, right, central) separately".

but the problem is that when we select unit cell atom and change to covalent it does not change the size of unit cell atom. Only scattering region atoms showing the atom size to covalent.

Please tell me how to show the whole scattering as well as unit cell atom size to covalent?

Like so
