| Abstract: | Within the tightly-binding Su-Schrieffer-Heeger (SSH) model and a nonadiabatic dynamic evolution method, we study the influence of the choice of zero electric potential energy on the charge injection in a metal/polymer structure. Through the theoretical calculation, we find that the influence of the choice of zero electric potential energy increases with the electric field strength increasing. |
