摘要：
The flexoelectric coefficients e(1) and e(3) for splay and bend are measured using two experiments. The first experiment measures the sum (e(1)+e(3)) using a pi-cell and applying an ac voltage across the device. The second experiment measures the difference (e(1)-e(3)) using a TN-cell and applying an in-plane quasi-do voltage.
