[Influence des effets capacitifs sur les performances dynamiques d'un CNTFET par la méthode Monte Carlo]
Le nanotube de carbone (CNT) est à ce jour l'un des candidats les plus prometteurs pour faire passer le transistor à effet de champ (FET) à l'échelle du nanomètre. Des recherches intensives sont en cours afin de déterminer les caractéristiques statiques et dynamiques des transistors à nanotube de carbone (CNTFET). Nous présentons dans cette étude des résultats de simulations de CTNFET par la méthode Monte-Carlo avec prise en compte des interactions électrons-phonons. Un des objectifs est de présenter les propriétés du transport pouvant être atteintes dans ce matériau par une évaluation du libre parcours moyen des porteurs. Une étude des caractéristiques statiques du CNTFET est réalisée et permet de mettre en avant l'influence du contrôle capacitif par la grille sur les performances. Enfin nous comparons les performances d'un CNTFET avec celles obtenues par simulation d'un transistor à nanofil de Silicium.
Carbon nanotubes (CNT) appear as a promising candidate to shrink field-effect transistors (FET) to the nanometer scale. Extensive experimental works have been performed recently to develop the appropriate technology and to explore DC characteristics of a carbon nanotube field effect transistor (CNTFET). In this work, we present results of a Monte Carlo simulation of a coaxially gated CNTFET, including electron–phonon scattering. Our purpose is to present the intrinsic transport properties of such material through the evaluation of the electron mean-free-path. To highlight the potential of the high performance level of CNTFET, we then perform a study of the DC characteristics and of the impact of capacitive effects. Finally, we compare the performance of CNTFET with that of a Si nanowire MOSFET.
