ion beam, either directly from an ion source or by sputtering from a tar-
get bombarded by ion beam. The percentage change of resistance of CNT
between 300 and 10 K was more than 600%. The drastic change in resistance
at low temperature indicates that CNTs grown on nickel lm can be used as
low-temperature sensors.
5.6 Laterally Grown CNT between Two Microelectrodes
as Resistive Temperature Nanosensor
The obvious question is: What is the reason for insistence on using CNTs? How
is the use of CNT as a temperature-sensing element benecial? In a complicated
thermal ow system, the perturba
