Piece of crude silicon rock
Silicon. Sample of crude-refined silicon. Silicon is a semiconductor group IV metal, with atomic number 14. It is not found as a native element, but is the second most abundant element in the Earths crust, occurring as silica (silicon dioxide). Crude silicon may be obtained by reducing silica with carbon in a furnace. Pure silicon is obtained by conversion to silicon tetrachloride, then reduction on a hot wire and zone refining. Exceptionally pure silicon is used as the substrate for electronic devices. Its diamond-type lattice structure means that it may be doped with electron donors or acceptors to form transistors and diodes

EDITORS COMMENTS
This print showcases a piece of crude silicon rock, representing the fascinating world of semiconductors. Silicon, belonging to group IV metals with an atomic number 14, is an incredibly abundant element in the Earth's crust. Although not found as a native element, it occurs abundantly as silica or silicon dioxide. The process of obtaining crude silicon involves reducing silica with carbon in a furnace. However, to achieve pure silicon for electronic devices, it undergoes several intricate steps. Firstly, it is converted into silicon tetrachloride and then reduced on a hot wire before undergoing zone refining. This meticulous procedure ensures that exceptionally pure silicon is obtained. What makes this material so remarkable is its diamond-type lattice structure which enables it to be doped with electron donors or acceptors. This property allows for the formation of transistors and diodes – crucial components in modern electronics. Captured by Science Photo Library, this image invites us to marvel at the raw beauty and potential held within this unassuming piece of rock. It serves as a reminder that even seemingly ordinary elements can possess extraordinary properties when harnessed through scientific exploration and innovation.
