[Pw_forum] Charged systems calculation

[sir_puding at tut.by]

Hi, All.

Maybe this is an rtfm-question, then sorry.

How can i calculate electronic structure of such charged system:
1. in general system in neutral, for example this it nanotube (closed)
2. we charge it by adding additional electrons from substrate/contacts
or other (for example polarize it by an external field. Field
emission)...

Then i want to calculate the conductance of this system.

Maybe someone know the way how to do this with espresso?
