Semiconductor technology

At low temperature, germanium is an insulator, while with the temperute increasing, it looses its insulating capacities.At low temperature, germanium is an insulator, while with the temperute increasing, it looses its insulating capacities.

Semiconductor technology

Chemistry makes it possible to transform silicon and germanium into semiconductors to power today's computers, appliances, and communication devices. Semiconductors, opposite to metals, are a class of materials that increase their conductivity by elevated temperatures. These semiconductors are further treated to create an excess or lack of electrons.

P type semiconductor

  1. Silicon
  2. Impurity (Gallium)
  3. Hole

N type semiconductor

  1. Silicon
  2. Impurity (Arsenic)
  3. Extra Electron

Computer chips and integrated circuits are made from semiconductors materials. Semiconductors enable electronic components to be smaller, faster, and more energy-efficient. Chemists in the semiconductor industry provide quality control of components, optimization processes, troubleshooting, and innovations to microelectronic devices.
