Dear Prof Nicola Marzari,
Sorry about the indistinct questions!
I want to calculate the superconducting Tc of
surface or thin film. So I need to calculate the
el-ph matrices and el-ph constants. It is necessary to
distinguish the contribution from bulk to the
contribution from surface. Am I right? Then I can
analyze why the Tc of film specimen is different from
the bulk specimen.
As you said, I am a newcomer in the field, and have
to do lots of homework about physics and computation.
And again thank you very much for your help in
patience.
Best regards!
Yingli Niu
