论文摘要
基本电子激发归因于库仑场散射，呈现出3D，2D，1D纳米管电子气体，石墨烯和碳纳米管中的各种现象。关键机制涵盖了尺寸依赖的裸库仑电位，能量分散和自由/价载体密度。它们负责主要特征，可用的激发渠道（电子孔区域），联合范霍夫奇异性，在小/足够高的转移动量上的未加压/抑制集体激发，等离子体频率的动量依赖（声学和光学模式）及其类别及其类别及其类别（内内和跨层元素）。各种系统之间存在某些显着的相似性和差异。 （动量/角动量，频率） - 激发相图直接反映在血浆波的传播中。
Elementary electronic excitations, which are due to the Coulomb-field scatterings, present the diverse phenomena in 3D, 2D, 1D-nanotube electron gases, graphene and carbon nanotubes. The critical mechanisms cover the dimension-dependent bare Coulomb potentials, energy dispersions, and free/valence carrier density. They are responsible for the main features, the available excitation channels (the electron-hole regions), the joint van Hove singularities, the undamped/damped collective excitations at small/sufficiently high transferred momenta, the momentum dependences of plasmon frequencies (acoustic and optical modes), and their categories (the intraband and inter-pi-band plasmons). There exists certain significant similarities and difference among various systems. The (momentum/ angular momentum, frequency)-excitation phase diagrams are directly reflected in the propagation of plasma waves.
