Observation of partially incoherent < 110 > boundaries between polar nanodomains in Na1/2Bi1/2TiO3 single crystals. Journal of Applied Physics, 108(6). doi: 10.1063/1.34888790021-8979http://hdl.handle.net/10919/52493The ferroelectric domain structure of Na1/2Bi1/2TiO3 single crystals was investigated by transmission electron microscopy (TEM) and piezoforce microscopy (PFM). Bright-field TEM and PFM images revealed the presence of polar nanodomains, whose boundaries had a tendency to align along the < 110 >. High resolution TEM images revealed planar defects along these < 110 > boundaries, which partially relaxed the coherency of the lattice. (C) 2010 American Institute of Physics.
