In this work we investigate the performance of cylindrical nanowire (CNW) and carbon-nanotube (CNT) FETs at their extreme miniaturization limits. The model self-consistently solves Poisson's and the quantum transport equations using the formalism of the Quantum Transmitting Boundary Method (QTBM). The performance comparison between CNW- and CNT-FETs with the same diameter demonstrates that the CNW-FET provides a better scaling trend at very low sizes. ©2007 American Institute of Physics

Abstract
In this work we investigate the performance of cylindrical nanowire (CNW) and carbon-nanotube (CNT) FETs at their extreme miniaturization limits. The model self-consistently solves Poisson's and the quantum transport equations using the formalism of the Quantum Transmitting Boundary Method (QTBM). The performance comparison between CNW- and CNT-FETs with the same diameter demonstrates that the CNW-FET provides a better scaling trend at very low sizes. ©2007 American Institute of PhysicsFile in questo prodotto:
