From the absorption spectrum, we found the indirect optical bandgap at 3.2 eV and the direct transitions around 4.5 eV in very good agreement with what has been predicted by theoretical calculations.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2012-07-03T15:46:19Z No. of bitstreams: 1 CC.pdf: 135124 bytes, checksum: e854a73d81d6a9200542f8330006d1f3 (MD5)Made available in DSpace on 2012-07-03T15:46:19Z (GMT).
