text: Specific heat capacity measurements by differential scanning calorimetry (DSC)
of single crystals of solid solutions of LiNbO3 and LiTaO3 are reported and compared
with corresponding ab initio calculations, with the aim to investigate the variation
of the ferroelectric Curie temperature as a function of composition. For this
purpose, single crystals of these solid solutions were grown with Czochralski
pulling along the c-axis. Elemental composition of Nb and Ta was investigated
using XRF analysis, and small samples with homogeneous and well known composition
were used for the DSC measurements. We observed that the ferroelectric Curie temperature
decreases linearly with increasing Ta concentration in the LiNb1−x Tax O3 solid
solution crystals. Furthermore, the ferroelectric transition width of a mixed
crystal appears to be smaller, as compared to pure LiTaO3.

text: Atomistic simulations in the framework of the density functional theory have
been used to model morphologic and vibrational properties of lithium niobate–lithium
tantalate mixed crystals as a function of the [Nb]/[Ta] ratio. Structural parameters
such as the crystal volume and the lattice parameters a and c vary roughly linearly
from LiTaO3 to LiNbO3, showing only minor deviations from the Vegard behavior.
Our ab initio calculations demonstrate that the TO1, TO2 and TO4 vibrational modes
become harder with increasing Nb concentration. TO3 becomes softer with increasing
Nb content, instead. Furthermore, the investigated zone center A1 -TO phonon modes
are characterized by a pronounced stoichiometry dependence. Frequency shifts as
large as 30 cm−1 are expected as the [Nb]/[Ta] ratio grows from 0 to 1. Therefore,
spectroscopic techniques sensitive to the A1 modes (such as Raman spectroscopy),
can be employed for a direct and non-destructive determination of the crystal
composition.

text: Confocal Raman spectroscopy was performed as an archetype imaging method to
study the ferroelectric domain structure of periodically poled lithium niobate.
More precisely, the linkage out of spatial resolution and spectral information
proved itself as very useful. Here a specific modulation of the Raman lines by
the local variation of polarity and a non-symmetric measuring-signal across the
domain structure were found, which allows for imaging of domain boundaries as
well as oppositely orientated domains. The high potential of this method is demonstrated
by the visualization of the ferroelectric domain structures based on various phonon
modes.

text: The vibrational properties of the LiNbO3 (0001) surfaces have been investigated
both from first principles and with Raman spectroscopy measurements. Firstly,
the phonon modes of bulk and of the (0001) surface are calculated by means of
the density functional theory. Our calculations reveal the existence of localised
vibrational modes both at the positive and at the negative surface. The surface
vibrations are found at energies above and within the bulk bands. Phonon modes
localised at the positive and at the negative surface differ substantially. In
a second step, the Raman spectra of LiNbO3 bulk and of the two surfaces have been
measured. Raman spectroscopy is shown to be sensitive to differences between bulk
and surface and between positive and negative surface. The calculated and measured
frequencies are in agreement within the error of the method.

text: We present results on ferroelectric micro-domains obtained by confocal second
harmonic microscopy. The high potential of this technique is demonstrated by imaging
periodic ferroelectric domain structures in the surface of planar X-cut lithium
niobate (LN) and in the body of ridges fabricated by plasma etching on X-cut LN
as well. In both cases the measured second harmonic signal reveals a strong contrast
between inverted and non-inverted domain sections. This enabled a depth-resolved
non-destructive tomography of micro-domains in ridge structures in all three dimensions.
