Here I am trying to calculate the Tc of material and electron-phonon coupling strength, but the Tc and lambda previously calculated are 14.1K and 1.1 respectively. So which parameters do I have to adjust to arrive at those values? One working with superconductivity DFT by quantum espresso can help me. here are my results attached.
I dont think it pays to try to be very acurate in superconductivity. There is too much uncertainty and different theories as BCS, Landau Ginzburg and so on. Then there is type I and type II superconductors, with or without a magnetic field, etc. That field takes a lot of study.
For example, Tc would normally just be measured.

You can try to use the equation given by the Eliashberg–McMillan relationship which is found in several textbooks, in that equation lambda and the function F are related. Probably you need to see if the ab initio program that you use calculates it. I guess so since you have lambda that comes from somewhere.
Kind Regards.
