Abstract
The present application provides a lithium niobate having a p-type nanowire region or an n-type nanowire region and a method for preparing the same. The method includes heating and then cooling a multi-domain lithium niobate crystal to confine hydrogen ions of the multi-domain lithium niobate crystal in domain wall regions; and poling the multi-domain lithium niobate crystal that has been heated by applying a voltage, to reverse a direction of polarization of one or more domains of the multi-domain lithium niobate crystal. The lithium niobate includes a lithium niobate crystal and a p-type nanowire region or an n-type nanowire region located in the lithium niobate crystal and adjacent to a surface of the lithium niobate crystal. The present application also provides a method for converting the charge carrier type of the lithium niobate nanowire region.
