Abstract

In this work, we report on the possibility of controlling the surface potential of extended-nano channels (ENCs) made in a system of SiO 2 /LiNbO 3 (LN), which can promote improvement of the proton diffusion rate. We detected the optimal thickness of a SiO 2 film which is ∼ 5 nm, where the deposited material would not affect spontaneous polarization of the LN material, which results in enhanced protontransport in ENCs. Here, we describe the device concept, the effect of SiO 2 thickness on the LN surface potential, demonstrate the device working principle and show its enhancement of 2.5 times in proton diffusion in comparison to the balk value.
