【摘要】Under the framework of Maxwell-Garnett (M-G) model, the optical and electrical properties of singlewalled carbon naotube (SWCNT), double-walled carbon nanotube (DWCNT) and hydrogen-doped carbon nanotube (H-doped CNT) in terahertz (THz) region have been investigated. It has been found that as frequency increases the loss tangent and conductivity show a peak. The loss tangent and conductivity of SWCNT is larger than that of DWCNT and H-doped CNT. The loss tangent and conductivity increase with the increases of falling factor and the decreases of geometrical factor. 【总页数】4页(161-164) 【关键词】
