I have do some calculations about a two-probe system, the transmission spectrum showns that there is a peak at 0.12eV in the zero voltage. However, according to the MPSH analysis, the energy of LUMO state is 2.20 eV, far from the Fermi level, and the energy of HOMO state is -0.18 eV, So, how can I address this peak? Someone told me that the LDOS analysis maybe do it ,but I do not know what information can be read from the LDOS. I post the results here with the hope that someone can help me.
