The double-helix structure, characterized by high-resolution transmission electron microscopy and X-ray diffraction, is completely different from the bulk atomic arrangement and may be considered a new structural phase of Se. Supporting ab initio calculations indicate that the observed encapsulated Se double-helices are radially compressed and have formed from free Se atoms or short chains contained inside carbon nanotubes. The calculated electronic structure of Se double-helices is very different from the bulk system, indicating the possibility to develop a new branch of Se chemistry.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-06-05T12:19:56Z No. of bitstreams: 1 10.1021-nn4019703.pdf: 1022921 bytes, checksum: 3a1a0e527b949af0525b3d61c406deb4 (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2014-10-10T15:14:50Z (GMT) No. of bitstreams: 1 10.1021-nn4019703.pdf: 1022921 bytes, checksum: 3a1a0e527b949af0525b3d61c406deb4 (MD5)Made available in DSpace on 2014-10-10T15:14:50Z (GMT).
