Post by: simba on September 30, 2009, 22:29

I have followed all the steps given in the tutorial of graphene junction device using ATKSE, when i see the contour of electron difference potential this is what i get.

This is a known issue, which occurs when using Mesa (default, generic) video drivers. You can solve it by installing vendor-specific video drivers (Nvidia, ATI, or whichever card you are using).

The problem has been fixed for the next release, so that VNL will support also Mesa.
