The remarkable optical and electronic properties of carbon nanotubes suggest new applications as photodectors, photovoltaic devices and nanoscale electronic biosensors. I will discuss the physics behind these applications, and recent progress towards realizing high performance devices. The photovoltaic mechanism for energy harvesting is very efficient in CNT devices, leading to excitement about solar energy applications. Our recent results demonstrate that a second mechanism, photo-induced thermoelectricity, also plays a critical role in the performance of suspended CNT optoelectronic devices [1]. Our investigations of nanoscale electronic biosensors focus on the ultimate limits of charge detection in biological environments. We have characterized the single-electron sensitivity of CNT biosensors and investigated the sources of background noise [2]. Current work is focused on recording single-enzyme dynamics in new systems.
