Semiconductor materials play an indispensable role in our modern information-oriented society. For reliable performance of semiconductor devices, these materials need to have superior mechanical properties: they must be strong as well as resistant to fracture, despite being rich in nanoscale structures.
Recently, it has become increasingly clear that the optical environment affects the structural strength of semiconductor materials. The effect can be much more significant than expected, especially in light-sensitive semiconductors, and particularly since due to technological constraints or fabrication cost many semiconductors can only be mass-produced in very small and thin sizes. Moreover, labora
