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.

Graphene has been one of the most vigorously studied research materials. We have developed a program for simulation of graphene field effect transistor (GFET). In this work, we use the simulation program to explore the performance of graphene FET. The simple model of the graphene FET is based on non-equilibrium Green’s function method and first is implemented by using graphic user interface of Matlab. The current-voltage characteristics of the GFET and affects of channel materials, gate materials, size of graphene FET, temperature on the characteristics are explored.

We provide a model of coaxial CNTFET, using single wall nanotube. These devices would exhibit wrap-around gates that maximize capacitive coupling between the gate electrode and the nanotube channel. The results of simulations of I-V characteristics for CNTFETs are presented. Here we use non-equilibrium Green’s function (NEGF) to perform simulation for CNTFET. This simulator also includes a graphic user interface (GUI) of Matlab that enables parameter entry, calculation control, display of calculation results. In this work, we review the capabilities of the simulator, summarize the theoretical approach and experimental results. Current-voltage characteristics are a function of the variables such as: diameter of CNT, the length of CNT, the gate oxide thickness, gate voltage of Vg, types of materials of Source-Drain, Gate, and temperature. The obtained I-V characteristics of the CNTFET are also presented by analytical equations.
