We have specified the mechanism of suppressed electron emission from surfaces bombarded by fast cluster ions. From key information obtained from a comparison of the electron emissions for insulator KCl and conductor graphite, we concluded that the suppression is predominantly caused by the disturbance of the electron transport by the electric potential generated by moving cluster atoms. The possible shift from suppressed emission to enhanced emission of electrons as cluster speed increases is also discussed in relation to that in the case of cluster stopping power.
