We find a strong optical response in the 0.5–2.0 eV region arising from optical absorption around the LW-line of the Brillouin zone. The response peak of the imaginary part of the dielectric functions at E = 1.6–1.8 eV shifts towards lower energies for high Sn compositions as a consequence of narrower W-point band-gap Eg(W) for the Sn-rich alloys.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2013-12-10T11:46:47Z No. of bitstreams: 1 10.1002pssa.200777747.pdf: 373965 bytes, checksum: 5871fc8a24cd8948590c4cd901b09b8d (MD5)Approved for entry into archive by Alda Lima da Silva (sivalda@ufba.br) on 2014-02-13T18:09:51Z (GMT) No. of bitstreams: 1 10.1002pssa.200777747.pdf: 373965 bytes, checksum: 5871fc8a24cd8948590c4cd901b09b8d (MD5)Made available in DSpace on 2014-02-13T18:09:51Z (GMT).
