The measurements were performed on 470 mm thick wafers. The OBGE obtained from both spectroscopies for different polytypes show very good agreement. In order to have a better understanding of these materials calculations of eletronic band structure were performed by the full-potential linearized augmented plane wave (FPLAPW) method. For the OBGE the results are compared to the measurements agreeing closely over the energies of those polytypes.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-20T10:30:59Z No. of bitstreams: 1 v6n1a09.pdf: 414785 bytes, checksum: cc9372355906b6ddf2fa88ad5994d769 (MD5)Made available in DSpace on 2011-12-20T10:30:59Z (GMT).
