Measurement of the Flexoelectric Coefficients e 1 and e 3 in Nematic Liquid Crystals

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 π-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...

Summary: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 π-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-dc voltage.
