The Langmuir-Blodgett film of fatty-acid is getten on the glass substrate.The Langmuir-Blodgett film is used as the orientation layer of 4-Pentyl-4'-Cyanodiphenyl(SCB)liquid crystal.The SCB liquid crystal is coated on the orientation layer under the condition of the rotation.The molecular hyperpolarizability(β)of 5CB liquid crystal is gotten with SHG method
β value of the measurement is in accordance with the document.
