Investigations on electrical properties and correlations to electron and X-ray energies of pyroelectric LiTaO 3 and LiNbO 3

The electrical properties of pyroelectric Lithium Tantalate (LiTaO 3 ) and Lithium Niobate (LiNbO 3 were investigated and compared to accessible X-ray energies by using the pyroelectric effect to generate X-rays. The capacitances of different crystals of varying sizes were measured and the resulting permittivities were calculated. A vacuum setup enabled a correlation to the maximum X-ray energies at a variable pressure. The presented results provide an overview of fundamental material properties and the effect on the generated difference of potential.
