Abstract
Carbon nanotubes (CNTs) have undergone intense scrutiny in recent years due to their potential as replacements for silicon technology. CNT field-effect transistors (FETs) have been achieved and shown to have superior electronic properties. One of the most important metrics in understanding and evaluating device performance is carrier mobility. Using a physics-based approach that takes into account various modes of scattering, multiple conduction bands, ambient temperature and CNT parameters such as diameter and length, analytical expressions for mean free paths can be derived. With these expressions we build a computationally efficient mobility model that accurately reproduces experimental behavior.
