Web21. nov 2011 · Abstract The size-dependent persistent photocurrent (PPC), which refers to a photocurrent persisting for a long time after the excitation light source is terminated, has been investigated in m -axial GaN nanowires (NWs) with diameters of 20–130 nm. These NWs possess polar side surfaces and thus exhibit strong surface band bending (SBB).
