Keep the light off: A material with improved mechanical performance in the dark

Researchers found that zinc sulfide crystals were brittle under normal lighting conditions at room temperature, but highly plastic when deformed in complete darkness. Deformation of zinc sulfide crystals in the dark also narrowed their band gap, which controls electrical conductivity. The team's findings showed the mechanical and electronic properties of inorganic semiconductors are sensitive to light, revealing a possible route to engineer the performance of inorganic semiconductors, which are important in electronics.
