In this work, the authors have used the FT-IR, Raman spectral analysis and dielectric measurements to determine the characteristic properties of multi-walled carbon nanotubes (MWCNTs) doped the lead-free pyroelectric material; polyvinylidene fluoride (PVDF): lithium tantalate (LiTaO) (hereon r...
In particular, we have studied the relaxation of the Li+ ions, which manifests itself on both the dielectric constant and the elastic constant by a peak in the imaginary part and a step in the real part. In the less concentrated crystal, the dielectric results are analyzed in the form of...

enabling dense integration of optical components on chip with a factor of 16 area density improvement over currently employed ridge waveguide structures for devices such as ring resonators. While a residual slab layer can improve the modulation efficiency due to the high dielectric constant LiNbO3, th...
