Unformatted text preview: Fermi energy is located in the center of the band, dividing the filled and empty states. The magnitude of the band gap, E G , determines whether the material is called a semiconductor or insulator. When the band gap, E G , is large the number of conduction electrons is very small. The conductivity is low and the material is an insulator. As E G decreases the number of conduction electrons increases. The conductivity becomes mea-surable and the material is called a semiconductor. Thank you for evaluating AnyBizSoft PDF Splitter. A watermark is added at the end of each output PDF file.
