AbstractA higher order nonlinear dielectric microscopy technique with higher lateral and depth resolution than conventional nonlinear dielectric imaging is investigated. The proposed technique involves the measurement of higher order nonlinear dielectric constants, with a depth resolution of down to 1.5 nm. The technique is demonstrated to be very useful for observing surface layers of the order of unit cell thickness on ferroelectric materials.

Superlattice structure of SrTiO3and Nb-doped SrTiO3have been epitaxially grown on atomically flat surface of LaAlO3substrates by ion beam deposition method. Epitaxial superlattices were grown at 800 °C in the presence of partial oxygen pressure under optimizing growth conditions. The Nb-doped SrTiO3layers were varied from 2 to 15 unit cell thickness approximately, while SrTiO3layers are maintained at 15 unit cell thickness with 10 periods. The superlattices with various Nb-doped SrTiO3layer thicknesses were investigated using X-ray diffractometer (XRD) and atomic force microscope (AFM), in order to clearly understand structural properties and surface structure, which are significant for fabrication of the high quality superlattice structure.
