I actually found a mistake in my original simulation featuring Au electrodes on the lithium niobate substrate. In my original simulation, the gold electordes were 1 nm above the LNO. I fixed the mistake and the simulation results are shown below. It looks like the simulation results are aligned with the literature reports for geometries featuring au gold electrodes on LNO. But when I introduce a Si brick between the electrodes and place it on LNO, I observe strong asymmetry. This result does not seem to be aligned with similar results in the literature (for example, see figure 2 of this paper https:\/\/www.mdpi.com\/2304-6732\/11\/10\/987). In my simulation, both LNO and Si are modelled as semiconductors.
