Silicon is a tetravalent metalloid element (atomic number 14) that forms the basis of most modern semiconductor technology and is a central topic across materials science, electronics, and solid-state physics. In crystalline form, it adopts a diamond cubic lattice, enabling precise control of its electronic band structure through doping with donors (e.g., phosphorus) or acceptors (e.g., boron) to create n- and p-type regions. Silicon’s indirect band gap, thermal stability, native oxide (SiO₂) formation, and compatibility with planar processing underpin integrated circuits, photovoltaics, and microelectromechanical systems, making it a foundational subject in research on electronic materials and device engineering.
A silicon device that can change skin tissue into blood vessels and nerve cells has advanced from prototype to standardized fabrication, meaning it can now be made in a consistent, reproducible way. As reported in Nature ...
