摘要: An extension (TR-PNP) of the traditional PNP model is proposed to explicitly taking into account effects ion trapping and release. Our approach this problem has originated from treatment introduced by Shockley, Read Hall in semiconductor theory. The release rate related calculated excess chemical potential (ECP) through Erying's Simulation results are presented for Gramicidin A channel using model, PNP-ECP TR-PNP-ECP compared with experiments.
