The material has been obtained by a mechanical alloying process. Due to its technological application, in high-performance bipolar transistors and integrated circuits, the interest in the physical properties of Si1−xGex has recently increased. The metal–nonmetal transition (for x=0.2) is determined to be 3.2×1018 cm−3. The optical band gap estimated from the absorption data at high boron concentration shows band gap narrowing when compared to the undoped alloy.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-01-24T10:24:43Z No. of bitstreams: 1 Silva.pdf: 169119 bytes, checksum: 1960ec9d5ff065ecfbaee1b9857de1f0 (MD5)Made available in DSpace on 2013-01-24T10:24:43Z (GMT).
