In Wiring Up Nanoelectronics, in MIT's Technology Review, Alan Leo writes "In the race to create ever-tinier electronic devices, nanowires are looking like a better bet. This month a team of Harvard researchers disclosed that they had created several functional nanoscale semiconductor devices, including the world's smallest bipolar transistor. Using silicon nanowires, semiconductive filaments only 20 nanometers wide, researchers in the lab of Harvard professor Charles Lieber also built a nanoscale diode and an inverter, the first devices ever assembled from both positive- and negative-type nanoscale semiconductors."
