Carbon Nanotube Transistor Compact Model

Single-walled Carbon Nanotube (CNT) Field Effect Transistor Device Modeling

We have developed a surface potential based compact model for the single-walled semiconductor CNT field effect transistor (CNT-FET) shown in Figure 1. Our compact modeling results for surface potential, channel charge, gate capacitance and channel current are shown in Figures 2-5 respectively. The model comparison is done using the numerical results of [1-4]. The compact model is developed for ...

Self-heating effect modeling of a carbon nanotube-based fieldeffect transistor (CNTFET)

We present the design and simulation of a single-walled carbon nanotube(SWCNT)-based field-effect transistor (FET) using Silvaco TCAD. In this paper, theself-heating effect modeling of the CNT MOSFET structure is performed and comparedwith conventional MOSFET structure having same channel length. The numericalresults are presented to show the self-heating effect on the I...

Performance Evaluation of Logic Gates Based On Carbon Nanotube Field Effect Transistor

Carbon Nanotube Field Effect Transistors (CNFETs) are being widely studied as the possible alternatives to the conventional silicon-MOSFETs. In this paper we have successfully designed the CNFET-based digital logic gates and compared them with the existing CMOS technology based logic gates. The designs are modeled using 32-nm technology for both CNFET and CMOS technology, using Stanford Univers...

Gate structural engineering of MOS-like junctionless Carbon nanotube field effect transistor (MOS-like J-CNTFET)

In this article, a new structure is presented for MOS (Metal Oxide Semiconductor)-like junctionless carbon nanotube field effect transistor (MOS-like J-CNTFET), in which dual material gate with different work-functions are used. In the aforementioned structure, the size of the gates near the source and the drain are 14 and 6 nm, respectively, and the work-functions are equal and 0.5 eV less tha...
