Surface step motion on the (001) surface of strontium titanate single crystals during DC electric field-assisted flash treatment" Vol.133, No. 11, The cover presents AFM topographic images of the (001) surface of SrTiO 3 single crystals after DC flash treatment.When the electric field is applied in the up-step direction, the stepterrace structure is stabilized, while application in the down-step direction results in step wandering and destabilization.Such step migration behavior suggests the role of drift diffusion of surface adatoms during the flash treatment, and also suggests that the athermal effects inherent to the flash event increase the surface adatom density and lead to step destabilization with extended treatment time.
