Why only silicon chip is used in - UCSB Science Line

Silicon is used because it can be used as either an insulator (doesn''t allow electricity to flow) or a semiconductor (allows a little flow of electricity). This is important for making chips. Also, it is very, very cheap. Answer 6: Yes; silicon is a semiconductor, which allows it to control the flow of electricity closely between the components

Polydimethylsiloxane - Wikipedia

Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones. PDMS is the most widely used silicon-based organic polymer due to its versatility and properties leading to many appliions.. It is particularly known for its unusual rheological (or flow) properties.

silicon | Element, Atom, Properties, Uses, & Facts

For use in electronic devices, single crystals are grown by slowly withdrawing seed crystals from molten silicon. Pure silicon is a hard, dark gray solid with a metallic lustre and with a octahedral crystalline structure the same as that of the diamond form of carbon, to which silicon shows many chemical and physical similarities. The reduced
