Abstract Carbon nanotubes (CNTs) are a promising material for high-performance electronics beyond silicon. But unlike silicon, the nature of the transport band gap in CNTs is not fully understood. The transport gap in CNTs is predicted to be strongly

Publikováno v: Physical Review Letters. 126

Electronic analogs of optical interferences are powerful tools to investigate quantum phenomena in condensed matter. In carbon nanotubes (CNTs), it is well established that an electronic Fabry-Perot interferometer can be realized. Other types of quan

Carbon nanotube (CNT) photodiodes have the potential to convert light into electrical current with high efficiency. However, previous experiments have revealed the photocurrent quantum yield (PCQY) to be well below 100%. In this work, we show that th

Carbon nanotubes continue to be model systems for studies of confinement and interactions. This is particularly true in the case of so-called "ultra-clean" carbon nanotube devices offering the study of quantum dots with extremely low disorder. The qu

Publikováno v: Environmental Science & Technology Letters. 2:118-122

Using a graphene field-effect transistor bio- sensor, we monitored the pH inside a living biofilm with fast temporal resolution (∼1 s) over multihour time periods. The atomically thin sensor is positioned between the biofilm and a supporting silico
