Identification of large polarons and exciton polarons in rutile and anatase polymorphs of titanium dioxide
Zhenbang Dai, Feliciano Giustino
Titanium dioxide (TiO2) is a wide-gap semiconductor with numerous applications in photocatalysis, photovoltaics, and neuromorphic computing. The unique functional properties of thi…
Theory of excitonic polarons: From models to first-principles calculations
Zhenbang Dai, Chao Lian, Jon Lafuente-Bartolome +1
Excitons are neutral excitations that are composed of electrons and holes bound together by their attractive Coulomb interaction. The electron and the hole forming the exciton also…
Excitonic polarons and self-trapped excitons from first-principles exciton-phonon couplings
Zhenbang Dai, Chao Lian, Jon Lafuente-Bartolome +1
Excitons consist of electrons and holes held together by their attractive Coulomb interaction. Although excitons are neutral excitations, spatial fluctuations in their charge densi…
