10/06/09 Dr. Kian Kaviani, Spring 2009, EE438L 3 Semiconductors: Silicon (Si) is the most important Semiconductor used in the integrated circuit (IC) industry with more than 88% of the electronic products rely on Silicon as the material of the choice. The first semiconductor used in the early 1940s to perform research on their electronic properties was Germanium (Ge). Silicon rather early in the stage of the material research replaced Ge due to the inferior electronic properties of Ge. In the early 1970 research in the Bell laboratories resulted in a whole new material system, namely Gallium Arsenide and its other alloys. Today the entire optoelectronic industry relies on group III – V semiconductors (I.e. GaAs, InP, AlGaAs, etc. .)
