Dear Sanjeev,

Mainly you should define your (nano)structure, i.e. atomic positions and then visualize them with XCrysDen.
Then see /examples/example07 and /examples/example15 directory how to set up parameters for such kind calculations.

But be sure, electron-phonon calculations are very time-demanding, especially for (nano)structures.
