Molecular Field Effect Transistor (MFET) is a promising alternative candidate of traditional MOSFET in future due to its small size, low power consumption and high speed. In this work, we introduce a model of three-terminal MFET. The structure of the MFET is in shape like traditional MOSFET, but its conductive channel is replaced by a benzene-1,4-dithiolate molecule. We use non-equilibrium Green's function method to compute transport function of charges and ultimately, the current-voltage (1-V) characteristics. The program is written by using graphic user guide (GUI) in Matlab. We have found significant difference of I-V characteristics between MOSFET and MFET. In addition, impacts of types of material, temperature, and bias on I-V characteristics of the MFET have been considered. Using GUI in Matlab, obtained results of simulations are intuitively displayed.
