While conductors exhibit low resistance and insulators feature high resistance, semiconductor materials are those that feature electrical conductivity values between the two. Semiconductors are produced from a number of compounds, common ones being gallium arsenide. They may also be produced with pure elements as well, such as germanium and silicon. With such materials, semiconductor devices may be produced and used for applications such as electronic circuit module fabrication, solar cells, laser diodes, and much more. As semiconductor devices and associated hardware serve as cornerstones of modern electronic manufacturing, having a general understanding of their functionality and types can be very beneficial.
