Domain patterning by strongly absorbed UV light in LiNb03 crystals

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.
