Total energies analysis indicate that the B/N pair tends to be doped at the edge of SiNRs and that the B/N pair doping in the armchair SiNRs (ASiNRs) is easier to carry out than the unbonded B/N pair doping in ASiNRs. Different from the metallic states associated with the singly substituted N or B atom at the edge in ASiNRs, the B/N bonded pair doping results in a semiconducting character, where the energy gap of ASINR can be adjusted, dependent on the B/N pair doping sites in ASiNR. For zigzag SiNRs (ZSiNRs), the introduction of the B/N pair results in a transition from nonmagnetic to spin-polarized states, which is attributed to the perturbation of pi and pi states localized at the doped ZSiNR edge. More importantly, the marvelous spin gapless semiconductor character with 100% spin polarized currents around the Fermi level has been obtaind, when the substitutional B/N pair located at the edge or subedge sites in ZSiNIts. These findings present a possible avenue for energy band and magnetism engineering in SiNR and benefit the design of silicene-based electronic devices. 入藏号:WOS:000321542000032 文献类型: Article 语种: English KeyWords Plus: TOTAL-ENERGY CALCULATIONS; WAVE BASIS-SET; MAGNETIC-PROPERTIES; GRAPHENE; SEMICONDUCTORS; HYDROGENATION 通讯作者地址: Zhang, CW (通讯作者) Univ Jinan, Sch Phys & Technol, Jinan 250022, Shandong, Peoples R China. 地址: [ 1 ] Univ Jinan, Sch Phys & Technol, Jinan 250022, Shandong, Peoples R China 电子邮件地址: zhchwsd@163.com 基金资助致谢: 基金资助机构 授权号 National Natural Science Foundation of China 61076088 11274143 60471042 Technological Development Program in Shandong Province Education Department J10LA16 [显示基金资助信息] 出版商:AMER CHEMICAL SOC, 1155 16TH ST, NW, WASHINGTON, DC 20036 USA Web of Science 类别: Chemistry, Physical; Nanoscience & Nanotechnology; Materials Science, Multidisciplinary 研究方向: Chemistry; Science & Technology - Other Topics; Materials Science IDS 号:179SQ ISSN:1932-7447 |
