Single-walled carbon nanotubes (CNTs) are among the most researched materials in the world. One of the foremost potential applications for CNTs is as the channel for next-generation transistors. In recent years the benefits of CNTs for future transistors have become more evident and accessible. It is important to note that the next generation of transistors will come in a variety of styles. There is the transistor that may replace silicon in the high-performance computing market. With the looming impossibility of further miniaturizing silicon transistors the tiny 1 nm diameter 1-D CNT provides a very promising alternative to overcome power constraints for continued transistor scaling. Is replacing silicon still realistic? Are the projected benefits of a high-performance CNT transistor technology worth the tremendous overhead cost? While definitive answers to these questions may be elusive, I will present recent results that must be taken into consideration. Finally, aside from high-performance computing, I will discuss some of the other next-generation transistor (and other nanoelectronic) applications that CNTs may be more suited, even uniquely poised, to facilitate. Aaron Franklin received his Ph.D. from Purdue University in 2008 and his B.S.E. degree from Arizona State University in 2004, both in electrical engineering. Since 2009, he has been a Research Staff Member at IBM's T. J. Watson Research Center working in the area of low-dimensional nanoelectronics.
