Abstract
It is shown that secondary electron emission current from ferroelectri c domains with opposite directions of spontaneous polarization in ferr oelectric KTiOPO4, crystals (KTP) is substantially asymmetric. The eff ect originates from asymmetry of elementary electron processes in nonc entrosymmetric crystals. A nondestructive method of ferroelectric doma in observation by secondary electron emission microscopy in KTP crysta ls is developed, which enables observation of a domain grating in peri odically poled KTP frequency doubler.
