Figure 4From: Vibration-assisted upconversion of molecular luminescence induced by scanning tunneling microscopySpectral functions of the molecule for ( a ) V = 0.0 eV and (b to e) V = 0.1 eV . The bias voltage is Vbias = 1.8 V. Here, (b) Tpl = 10-4 and ℏ ω p =2.05eV, (c) Tpl = 10-2 and ℏ ω p =2.05eV, (d) Tpl = 10-4 and ℏ ω p =1.25eV, and (e) Tpl = 10-2 and ℏ ω p =1.25eV.Back to article page
