3.1.3 Ultra-low Power Single-walled Carbon Nanotube Based Chemical Sensors

K. Chikkadi, C. Roman & C. Hierold
In the last decade, Single-walled Carbon Nanotubes (SWNTs) have emerged as potential functional materials in next-generation chemical sensors due to their exceptional electronic and chemical properties. In this review, we summarize the progress that has been made in the last few years in the field of carbon nanotube chemical sensors. When a single SWNT is integrated as the channel in a carbon nanotube field-effect transistor (CNFET), ultra-low power operation down to 0.01 μW and a...
