The polarization switching field is found to decrease with the ZnO doping with a threshold (Eth) and internal (Eint) field as low as 2.5 and 0.5 kV/mm, respectively, resultant on 8 mol % ZnO doped LiNbO3. The substantial decrease of Eth and Eint is ascribed to the suppression of nonstoichiometric point defects by the substitution of Zn2+ ions in the lattice site. © 2001 American Institute of Physics.application/pdf146909 bytesapplication/pdfen-USjournal article10.1063/1.13368152-s2.0-0012542890http://ntur.lib.ntu.edu.tw/bitstream/246246/145994/1/06.pdf
