摘要： One of the perspectives of the Si-based technology is the optical interconnect for data transmission and applications in optoelectronic integrated circuit. In this report, the engineered dislocation network was proposed, and the atomic structure of the dislocation array was revealed by high-resolution transmission electron microscope and scanning tunneling microscope. The photoluminescence emission is strong and compatible with intrinsic Si characteristic peak, making it possible as light emitters in silicon. The analysis of dislocation array-induced scanning tunneling spectroscopy identified the presence of defect levels under the conduction band, compared with the occupied and unoccupied Kohn-Sham orbitals in the forbidden gap of Si derived from first-principles theoretical models. This study demonstrated the possibility of dislocation-induced optical transition from a theoretical and experimental perspective, which will be essential in the development of Si-based optoelectronic integrated circuit. 其他題名： TNANO 出版者： IEEE 出版日期： 2015-05-01 出處： IEEE transactions on nanotechnology, 2015-05, Vol.14 (3), p.399-403 資源來源： IEEE Electronic Library (IEL) 識別號： ISSN: 1536-125X 識別號： EISSN: 1941-0085 識別號： DOI: 10.1109/TNANO.2015.2411292 識別號： CODEN: ITNECU
