| 2. | Two kinds of deriving to debye ' s density of states in solid state theory 固体理论中德拜态密度的两种推导 |
| 3. | Density of states for one - dimensional photonic crystal composed of alternative left - handed and right - handed materials 左右手材料构成的一维光子晶体的态密度 |
| 4. | The computations showed that , under some conditions , there appeared some unusual densities of states in the band gaps 计算表明:在一定条件下,禁带中出现了非寻常的态密度。 |
| 5. | Consequently , the energy band structure and the densities of state were researched . secondly , vas - cdgeas2 and ge / as - cdgeas2 were upbuilded 用红外光谱仪在中红外区做吸收检测,结果显示晶体在中红外区的吸收较低。 |
| 6. | Secondly , density of states for metallic carbon nanotubes with a magnetic impurity is studied based on a single orbital anderson model 其次,引入anderson模型和快速收敛的微扰展开方法研究了单个磁性杂质对碳纳米管态密度的影响。 |
| 7. | Firstly , the influence of point defects on the density of states and conductance for metallic carbon nanotubes is studied based on the tight - binding model 首先,基于紧束缚模型研究了非磁性点缺陷对金属型单壁碳纳米管态密度和电导的影响。 |
| 8. | From an analytic treatment , the state is determined by the nanotube diameter rather than chirality . the corresponding image of local density of states in real space shows a highly localized state around the defect 然后逐点计算局域态密度发现,在实空间准束缚态是一个非常局域化的效应,离开缺陷即迅速衰减。 |
| 9. | These unusual densities of states were due to the discrete propagation modes peculiar to the photonic crystal composed of alternative left - handed and right - handed materials , and could be used to make very narrow filters totally different from any conventional types of filters 这些禁带中的态密度是由左右手材料构成的一维光子晶体所特有的,它们可用于制造完全不同于常规滤波器的、频带狭窄的新型滤波器。 |
| 10. | This paper derived the transfer matrix of the bilayer structure composed of left - handed and right - handed materials , and computed the density of states ( dos ) along the axis of the finite one - dimensional photonic crystal , which was constructed out of n such bilayer structures periodically 摘要推导出了由左右手材料构成的双层结构的转移矩阵,计算了由n个该双层结构周期性排列所形成的一维有限长度光子晶体沿其轴线方向的态密度。 |
