Abstract

In this paper, the authors have illustrated a new kind of devices (molecular devices), able to work better at nanometer scale, with particular attention to molecular diodes. In particular, the I-V characteristics of a gated molecular diode were simulated, showing how an increase of the gate voltage involves an increase of the drain current. Then they proposed a simulation study which is obtained by SPICE simulator, in order to analyze and design some basic digital circuits (AND & OR) employing molecular diodes. In the light of obtained results, the molecular diodes are demonstrated as logic ports cannot be used because, although they follow input pulses, the logic levels in output and the noise margin obtained are not appropriate for electronic applications.
