Electronic transport computations have been carried out in the bias voltage range valued from 0.0 to +2.0 V divided by 0.1 V step-sized intervals and under the gate potentials including -3.0, 0.0 and +3.0 V. The Current-bias curves at the considered bias and gates potential show regions with negative differential resistance (NDR).
