Impact of the nanotube diameter on the performance of CNFETs

This study investigates 38 CNFETs and shows that nearly 3 orders of magnitude current variation can be explained in a comprehensive way by the diameter variation among nanotubes alone. This is the first systematic analysis that correlates the device performance with the nanotube properties quantitatively. It also shows that one can neglect the impact of the preparation on the contact quality to a large extend
