Investigating Quantum Processes in Disordered Materials
… exponential sub-gap absorption tail known as the Urbach tail. By laying the foundational principles of capturing Urbach tails using DFT in two well-studied semiconductors, we retrieve the role of particular phonon modes, the localisation of Urbach tail states, the role of long wavelength phonon …
