How Semiconductor is Revolutionizing the World

Prior to semiconductors, engineers depended on vacuum tubes. Although these were functional, the tubes used a massive amount of power, produced a lot of heat, and often failed.

Fremont, CA: When transmitting electricity, materials are distributed into three groups, which are conductors, insulators, and semiconductors. Copper wire in a home’s wall is labeled as a conductor because it transmits electricity easily. Rubber or ceramic are insulators that prevent electricity transmission.

Semiconductors can be considered as insulators as well as conductors, depending on the circumstances. Heat is the deciding factor as semiconductors become more conductive as their temperature increases. In certain applications, engineers also use superconductors that increase their conductivity as temperature decreases.

Semiconductors have helped modern technology exist. Prior to semiconductors, engineers depended on vacuum tubes. Although these were functional, the tubes used a massive amount of power, produced a lot of heat, and often failed.

Circuit technology is reaching a tipping point where I can no longer advance. Designers cannot fit any more transistors into a small space. However, modern engineers have started researching possible nanotechnology application that uses carbon nanotubes to create processors and circuits that are smaller and advanced. Nanotechnology could potentially shirk technology even more, pushing humanity into a future of implantable smartphones and mind-machine interfaces.
