%T Electric field induced SHG in PZT thin films studied using near-field scanning optical microscopy
%V 88
%X Near-field second harmonic microscopy was applied to imaging of the metal-PZT-metal structure, good contrast between metal and ferroelectric part has been observed. SHG dependence on electric field has been measured locally. © 2002 Optical Society of America.
