Langevin-Type Charge Carrier Recombination in a Disordered Hopping System


  • Postfach. D-35032 Marburg, Federal Republic of Germany.


A Monte Carlo simulation study is performed to determine the ratio γ/μ of the rate coefficient for bimolecular charge recombination and the charge carrier mobility in a hopping system with built-in energetic disorder. The result indicates that γ/μ is independent of disorder but increases at large electric fields at which the charge carrier velocity saturates.
