Mesoscopic physics explores quantum phenomena through electron transport at the nanoscale. One key effect is current noise, which becomes prominent at this scale and reveals important physical insights. A previous study on carbon nanotubes (CNTs) showed that power spectral density (PSD) of phonon-induced current noise follows a Lorentzian distribution and exhibits high-frequency peaks that are attributed to resonance with specific phonon modes. In this study, to verify this interpretation, I redeveloped the OpenTDSE+MD simulator by replacing the conventional Tersoff potential with an Einstein phonon model that excludes these intrinsic phonon modes.
