Dear PWSCF users,<br>
<br>
I am using Quantum espresso package for DFT calculation for noble nitride systems. My main interest in electron-phonon calculation and Raman tensor etc. Sir, I want to know, what will be change in SCF or NSCF file for nanostructures calculation? or where is difference in bulfk or nano? I want to do calculation on nanostructre?, what i do ?<br>
Please help me .<br>
<br>
Kind Regards<br>
