The high‐temperature transport properties of individual carbon nanotubes (CNTs) with a specified chiral index have been studied by Peng Liu, Kaili Jiang, and co‐workers in article number 2000103 . Experimental results show that the resistivity increases with temperature T monotonically, the carrier concentration exponentially increases with 1/ T , and the mobility decreases as the temperature increases. The mobility of CNTs at high temperature exhibits a deviation from the traditional trend, which can be attributed to the dominant electron–optical phonon interaction at high temperature. The temperature dependence of mobility deviates from the linear relation with T − β at low temperature to exp( α/T ) at high temperature. The results are discussed within a polaron model.
