Rigorous modeling of carbon nanotube transistors

Rigorous modeling of carbon nanotube transistors

Based on the non-equilibrium Green’s function formalism the performance of carbon nanotube field-effect transistors has been studied. The effects of elastic and inelastic scattering on the device performance have been investigated. The results indicate that elastic scattering has a more detrimental effect on the device characteristics than inelastic scattering. Only for short devices the perfor...

Modeling of Carbon Nanotube Field Effect Transistors

Modeling of Carbon Nanotube Field-Effect Transistors

In this thesis, models are presented for the design and analysis of carbon nanotube field-effect transistors (CNFETs). Such transistors are being seriously considered for applications in the emerging field of nanotechnology. Because of the small size of these devices, and the nearone-dimensional nature of charge transport within them, CNFET modeling demands a rigorous quantum-mechanical basis. ...

Application of Neural Space Mapping for Modeling Ballistic Carbon Nanotube Transistors

In this paper, using the neural space mapping (NSM) concept, we present a SPICE-compatible modeling technique to modify the conventional MOSFET equations, to be suitable for ballistic carbon nanotube transistors (CNTTs). We used the NSM concept in order to correct conventional MOSFET equations so that they could be used for carbon nanotube transistors. To demonstrate the accuracy of our mod...

Towards Multi-Scale Modeling of Carbon Nanotube Transistors

Multiscale simulation approaches are needed in order to address scientific and technological questions in the rapidly developing field of carbon nanotube electronics. In this paper, we describe an effort underway to develop a comprehensive capability for multiscale simulation of carbon nanotube electronics. We focus in this paper on one element of that hierarchy, the simulation of ballistic CNT...
