gallium

ga lee uhm

  • n  a rare silvery (usually trivalent) metallic element; brittle at low temperatures but liquid above room temperature; occurs in trace amounts in bauxite and zinc ores

  • HelioVolt didn't invent copper indium gallium selenide, a thin film used to generate electricity from sunlight, but it did develop a faster, more cost-effective way to manufacture .
  • Different semiconductor materials produce different colors; Nakamura used gallium nitride, which generates blue and white light.
  • The raw materials the workers carry are ultra-thin sheets of flexible plastic, which are then coated with a series of chemicals--indium, gallium, diselenide--that allows the module .
