✅ Identification of large polarons and exciton polarons in rutile and anatase polymorphs of titanium dioxide

science

Titanium dioxide (TiO(2)) is a wide-gap semiconductor with numerous applications in photocatalysis, photovoltaics, and neuromorphic computing. The unique functional properties of this material critically depend on its ability to transport charge in the form of polarons, namely narrow electron wavepackets accompanied by local distortions of the crystal lattice. It is currently well established that the most important polymorphs of TiO(2), the rutile and anatase phases, harbor small electron...
