Crystal structure of germanium and silicon
WebGermanium was critical for the first wave of semiconductors until replaced by silicon in the 1970s, but is still used for very high-performance devices such as quantum computers. Some germanium oxides are opaque to light but transparent to infra-red, so are used as windows and lenses for night vision and thermal imaging.
