In recent experimental work it was found that for a current–voltage bistability in/an organic semiconductor working as multilevel switching (B. C. Das and A. J. Pal, Organ. Electron. doi: 10.1016/j.orgel.2007.07.008). Due to the experimental motivation, we simulate the electronic distribution properties as charge accumulation/depletion-voltage and capacitive effects-voltage of a similar organic compound by means of the quantum mechanics methodology. Also, our theoretical results are consistent with: (i) similar behavior for positive bias when compared with experimental one; (ii) prediction as asymmetric feature for negative bias, e.g., asymmetric majority carrier transportation curve for Ponceau SS device; (iii) resonance tunneling type conduction in the I–V signature. For both bias (positive and negative) the resonance is addressed and it explains as a bi-directional molecular transistor or memory device.
