so how would band diagram look like @Jemurray3

Consider what kind of potential would yield such an electric field diagram, then basically tack it on to the band diagram.

that would be integral of the that?

ok, got it , and this is v vs x graph how do we go to band diagram?

In the absence of a field, the band diagram may look like this:

so how does electric field alter it

If you add an constant electric field pointing to the right, that means that the energy of a positively charged particle would be higher on the left than on the right so the bands would shift:
