我在Plasmonics: Dispersion relation中提到了SPPs的两种激发方式:光栅/棱镜激发。这两种激发方式非常常见,但都属于光学激发的范畴。其物理图像是:通过引入额外的结构(动量)实现光子与SPPs间的动量匹配。 这篇文章我就来讲讲SPPs的电学激发——非弹性电子隧穿(inelastical electrons tunneling,IET)。需要注意,这种激发方...
In general, any process separating radiation into components having different frequencies, energies, velocities, or other characteristics, such as the sorting of electrons according to velocity in a magnetic field. (statistics) The degree of spread shown by observations in a sample or a population....

of the electrons, the phenomenon of resonance arises, bringing about the dependence of ε on frequency, as well as the absorption of light. This theory explains well the relationship between dispersion of light and the absorption bands. To obtain quantitative agreement with experimental values, in ...
(DM) The number of electrons per unit volume,ne, integrated along the line of sight to a source: DM =nedl where dlis an element of the path. It is the factor that determines, for example, the time delay (i.e.dispersion) between the arrival of radio pulses from apulsarat two differen...
A paradigmatic member of this class is the fluid of exciton–polaritons (polaritons), that can be pumped within the spacer of an optical microcavity in the strong coupling regime12. Polaritons can be understood as photons dressed by semiconductor electrons–hole pairs (excitons) that display ...
The IAW electric field parallel to B accelerates electrons up to about 10 keV along B. The IAW dispersion relation quantifies the precipitating electron striation observed with high-speed cameras as spatiotemporally dynamic fine structured... M Hirsch 被引量: 0发表: 2017年 加载更多来源...
