Inhomogeneities in the energy bands of semiconducting carbon nanotubes (CNTs) are investigated with scanning gate microscopy (SGM). Non-uniform responses of a semiconducting CNT to a local electric field are found in SGM images which are obtained at the different depletion states of the CNT. The results indicate that local potential perturbations affect the transport characteristics of semiconducting CNTs significantly, especially near the off-state of the device.
