Fig. 3: Mechanical measurements and high flexibility of s-BAs.

From: Flexible thermal interface based on self-assembled boron arsenide for high-performance thermal management

Fig. 3

Representative stress–strain experimental curves for: a Young’s modulus and b shear modulus measurements, with varied loading ratios. c The Young’s modulus and shear modulus of s-BAs. The solid symbols are experimental data, and the shadowed backgrounds represent the modeling results considering varied extents of alignment. d Optical images of the highly flexible s-BAs. Inset on the bottom left, indicates the original size. e Bending tests and thermal conductivity measurement of s-BAs in response to the cyclic bending.
