|Title:||Magnetism in BN nanotubes induced by carbon doping||Authors:||Wu, R.Q.
|Issue Date:||21-Mar-2005||Citation:||Wu, R.Q., Liu, L., Peng, G.W., Feng, Y.P. (2005-03-21). Magnetism in BN nanotubes induced by carbon doping. Applied Physics Letters 86 (12) : 1-3. ScholarBank@NUS Repository. https://doi.org/10.1063/1.1890477||Abstract:||We performed ab initio calculation on the pristine and carbon-doped (5,5) and (9,0) BN nanotubes. It was found that carbon substitution for either a single boron or a single nitrogen atom in the BN nanotubes can induce spontaneous magnetization. Calculations based on density functional theory with the local spin density approximation on the electronic band structure revealed a spin polarized, dispersionless band near the Fermi energy. The magnetization can be attributed to the carbon 2p electron. Compared to other theoretical models of light-element or metal-free magnetic materials, the carbon-doped BN nanotubes are more experimentally accessible and can be potentially useful. © 2005 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/97134||ISSN:||00036951||DOI:||10.1063/1.1890477|
