摘要: An improved general theory of electronic transport in molecular crystals with local linear electron–phonon coupling is presented. It valid for arbitrary and phonon bandwidths strength, yielding small‐polaron narrow bands strong coupling, semiconductor wide weak coupling. Detailed results are derived excitations fully clothed phonons having a bandwidth no larger than the frequency; densities states taken as Gaussian simplicity. The dependence diffusion coefficient on temperature other parameters analyzed thoroughly. calculated behavior provides rational interpretation observed trends magnitude charge‐carrier drift mobilities crystals.
