When indented by a probe in darkness, wafers of some semiconductors are putty-like. When illuminated by light whose wavelength matches the band gap, they become hard, as electrons and holes freed by ...

Despite being composed of solid rocks, the Earth's mantle, which extends to a depth of ~2890 km below the crust, undergoes convective flow by removing heat from the Earth's interior. This process ...
