Three new tutorials have been published, including one on single electron transistor calculations with ATK 2010.01!
The best way to get started with ATK and VNL is to go through the manuals and the tutorials. Recently three new tutorials were published:
A basic tutorial on transport in graphene nanoribbons, designed as an introduction to ATK and VNL 2010.01
An advanced tutorial dealing with a benzene single electron transistor (SET), operating in the Coulomb blockade or sequential tunneling regime
Another more advanced tutorial on graphene, intended to teach users more about the scripting language, and how to extend the functionality of VNL with Custom Builders
