Thanks for any … Webintegrals are negligible unless b = b0, i.e. that electron-phonon interactions cannot excite an electron from one band to a di erent band. This is usually justi ed by the fact that the typical phonon energies are much smaller than the gaps between bands { but in materials where this is not true, one must keep inter-band transitions as well. WebIntroduction. ALAMODE is a scientific software designed for analyzing lattice anharmonicity and lattice thermal conductivity of solids. By using an external DFT package such as VASP and Quantum ESPRESSO, you can extract harmonic and anharmonic force constants straightforwardly with ALAMODE. Using the calculated anharmonic force constants, you ... alberto lebrun munera
