H Choi, EK Lee… - Current Applied Physics, 2011 - Elsevier ... The total D value decreases with strain in [1 0] as the x- component, Dx, sharply decreases as adequately compensating up the smooth increment of the y- component D, Dy (Figure 1(a)). Accordingly, the ratio of Dx to Dydrops below 1 when the strain exceeds 3%, which means ...
