Bias voltage dependence of the vibrational occupation number and the population of the molecular exciton. Red solid and green dashed lines refer to the vibrational occupation number for vibrational state in nonequilibrium and thermal equilibrium, respectively. The blue dashed-dotted line refers to the population of the molecular exciton. Here, (a, b) Tpl = 10-4 and ω p =2.05eV, (c, d) Tpl = 10-2 and ω p =2.05eV, (e, f) Tpl = 10-4 and ω p =1.25eV, and (g, h) Tpl = 10-2 and ω p =1.25eV. The exciton-plasmon coupling is V = 0.10 eV.
