Domain patterning by strongly absorbed UV light in LiNb03 crystals
Domain patterning by strongly absorbed UV light in LiNb03 crystals
Short-term exposure of the surface of lithium niobate crystals to focused strongly absorbed UV light leads to persistent inhibition of subsequent ferroelectric domain reversal on the +z face at the irradiated site. The same procedure can be adopted to directly generate domains on the non-polar faces. Investigation of the UV-irradiated tracks by piezoresponse force microscopy reveals the connection between the inhibited domains on the +z face and local lithium depletion, while thermoelectric fields can be invoked to generate the domains on the non-polar faces.

Abstract
Short-term exposure of the surface of lithium niobate crystals to focused strongly absorbed UV light leads to persistent inhibition of subsequent ferroelectric domain reversal on the +z face at the irradiated site. The same procedure can be adopted to directly generate domains on the non-polar faces. Investigation of the UV-irradiated tracks by piezoresponse force microscopy reveals the connection between the inhibited domains on the +z face and local lithium depletion, while thermoelectric fields can be invoked to generate the domains on the non-polar faces.
