WebMay 16, 2011 · Those unstretched and unpoled films were cut into two kinds of pieces with the rectangle shape and the trapezoid shape, respectively. The Youngʼs modulus, E, of the films was measured from the rectangle shape film via the Lock-in detection setup shown in Fig. 2 (b), and we obtained an approximate value of E ≈ 3.13 × 10 9 N / m 2.The direct … WebThe flexoelectric effect is more pronounced in more complex phases: the three-layer phase, the four-layer phase and the six-layer phase. In this chapter we consider several important aspects of the flexoelectric effect for chiral polar smectic liquid crystals and for the variety of phases. First, we discuss the reason for indirect interlayer ... cost base for tabcorp demerger
