(color online) Electronic transport properties of the molecular junction for the triple bond of TADHA molecule being fluoridated by F₂ molecule. (a) Current and differential conductance as functions of applied bias voltage. (b) Transmission spectra for fluoridated TADHA molecular junction at different bias voltage. The dashed lines in panel (a) are the corresponding curves of TADHA molecular junction without F₂ adsorbate, and the red dashed line in panel (b) is the transmission spectrum of TADHA molecular junction without F₂ adsorbate at 0.25 V, which are used as reference curves in the figures.
