A universal Urbach rule for disordered organic semiconductors
The sub-gap absorption coefficient in organic semiconductors is often characterized by Urbach energies, which quantify both structural and dynamic disorders, yet the fundamental is not well-understood. Here, the authors provide a strategy to determine excitonic disorder energy, and reveal that absor...
