Using electrostatic force microscopy, we show direct evidence of charge injection at the carbon nanotube–SiO2 interface leading to the appearance of hysteresis. The dynamic screening effect of the injected charges is revealed step by step. Further temperature dependent tests also demonstrate the eff...
