【摘要】 碳纳米管对光的吸收与光的偏振方向有关,光偏振方向与碳纳米管管轴方向平行时光吸收最强,光偏振方向与碳纳米管管轴方向垂直时光吸收最弱。采用半经典理论处理光和碳纳米管的相互作用,计算了碳纳米管的光吸收与光偏振方向的关系,计算结果表明碳纳米管光吸收速率与cos~2θ成正比,其中θ是光偏振方向和碳纳米管轴向夹角。更多还原

【Abstract】 The optical absorption of carbon nanotubes(CNTs)has relation with optical polarization direction. The optical absorption is maximum when optical polarization direction is parallel to the axis of CNTs.The optical ab- sorption is minimum when optical polarization direction is perpendicular to the axis of CNTs.The interaction of optical wave and CNTs is discussed based on the semi-classical theory.The relation between optical absorption of CNTs and optical polarization direction is calculated.The calculation result indicates that the absorption rate is proportional to cos~2θ,whereθis the angle between optical polarization direction and the axis of CNTs.更多还原
