Polarons are quasiparticles composed of excess electrons dressed with virtual phonon clouds. They are ubiquitous in materials and play a key role in various physicochemical properties, including superconductivity, photocatalysis and ferroelectricity. However, carrier mobility is reduced when polarons are formed due to strong carrier localization, which degrades the performance of electrical devices, and an effective strategy to solve this problem is still lacking.
