WebApr 17, 2009 · We present a theory for spin diffusion in disordered organic semiconductors, based on incoherent hopping of a charge carrier and coherent precession of its spin in an effective magnetic field, composed of the random hyperfine field of hydrogen nuclei and an applied magnetic field. From Monte Carlo s … WebThe concept of hopping transport has been familiar for a long time in connection with ionic conduction, since ions move essentially by hopping, whether through interstices or vacancies. This concept has been extended to electrons, particularly for electronic conduction in amorphous and disordered nonmetallic solids. 4, 34

WebOct 21, 2013 · The polaron approach is capable of bridging the results from the coherent band-like transport regime governed by the Redfield equation to incoherent hopping transport in the classical regime. Additionally, a non-monotonic dependence of the diffusion coefficient is observed both as a function of temperature and system-phonon coupling … WebMay 22, 2024 · The CT mechanism changes from slow hopping of a fully localized charge to fast diffusion of a polaron delocalized over several molecules as electronic coupling between the molecules exceeds the critical threshold V ≥ λ/2 (λ is the reorganization energy). ...
