Semiconductors

Type: Concept

As of November 2026, Semiconductors has been mentioned in one podcast episode on The Diary Of A CEO (Apr 2026). Semiconductors are discussed in relation to their critical role in technology and the impact of helium shortages.

A semiconductor is a material with electrical conductivity between that of a conductor and an insulator. Its conductivity can be modified by adding impurities ("doping") to its crystal structure. When two regions with different doping levels are present in the same crystal, they form a semiconductor junction. The term "semiconductors" is sometimes used to refer to semiconductor devices such as microchips and computer processors, which work using the physical properties of semiconductors.
