Abstract :
Direct measurements on the electronic transport in a single carbon nanotube (CNT) were carried out inside the scanning electron microscope (SEM) using a nanoprobes system. Good contacts have been established between the probing nanotip and the CNT, and field effect on the current-voltage (I-V) curves has been demonstrated using a nanoprobe as a gate. Our results show that by using a nanoprobes system it is possible to perform reliably the electronic transport measurements on nanostructures of various shape and composition that are visible in the SEM.
