[LCTp1-4] Novel Measurement Method for Difference of Flexo-coefficients (e11-e33) by Using Disclination Lines in HAN Cells with Concentric Rubbing Treatment
Flexoelectric, Flexo-coefficients, e11-e33, Concentric rubbing
We propose a novel evaluation method for the difference of flexo-coefficients ’e11-e33’. A HAN cell with in-plane electrodes treated concentric rubbing is used. Positions of disclination lines which occur due to the flexo-polarization under applying the dc electric field are used for evaluating e11-e33 with fitting of numerical calculated results.
