Microscope image of bending flexible InGaAs detector: (a) Bending up of R = 10 mm. (b) A magnified view of the outline area on the left shows the cracking failure surface. (c) Bending down of R = 10 mm shows the appearance of the delamination failure. (d) Bending up of R < 10 mm shows the expansion of the delamination failure.
