Here we use momentum-selective high-resolution electron energy loss spectroscopy to atomically resolve the phonons at the FeSe/STO interface. We uncover new optical phonon modes, coupling strongly with electrons, in the energy range of 75–99meV. These modes are characterized by out-of-plane ...

The macroscopic and microscopic analyses of phonon modes that has been done in past works for two-dimensional quantum wells are developed in this work for one-dimensional quantum wires. Inconsistencies and errors in past works on phonon modes in quantum size structures are discussed including the co...
The equation of motion for the p-polarization field in an arbitrary wurtzite multilayer heterostructure is solved for the propagating optical-phonon (POP) modes in the framework of the dielectric-continuum model and Loudon's uniaxial crystal model. The polarization eigenvector, the dispersion relation...
采用Judd-Ofelt理论计算了0.9Ge30Ga5Se65+0.1CsBr玻璃样品中Dy3+ 跃迁的强度系数、自发辐射几率与荧光分支比. 为了研究多声子弛豫(MPR)随温度的变化, 测试了Dy3+ 的6H11/2 能级在20～300K温度范围内的荧光寿命, 分析了Ge30Ga5Se65玻璃中声子模式与电子-声子结合强度对Dy3+ 1.72μm处荧光强度和效率的影响. ...
Electron–phonon scatterings in solid-state systems are pivotal processes in determining many key physical quantities such as charge carrier mobilities and thermal conductivities. Here, we report direct probing of phonon mode specific electron–phonon sc
electron-phonon coupling 电声耦合，电子-声子耦合 最为一般的理解就是电子与原子核之间的相互作用。因为声子指的就是考虑了核的振动效应，这是电子和原子核之间就会有相互作用。
Basic properties of the phonon modes and carrier-phonon interactions are considered in the basis of this treatment of dimensionally-confined phonons in wurtzite structures. A key feature of these phonon modes is their enhanced dispersion and its origin from the non-isotropic nature of the wurtzites...
摘要: Ab initiocalculations of the phonon spectrum, spectral function of the electron-phonon interaction, and transport properties (resistivity) of technetium are carried out in the framework of linear response theory. Good agreement with the experimental data is obtained....
Due to the electron–phonon interaction the phase diagram of the interacting electron system changes remarkably. In dependence on the phonon frequency and on the electron–phonon coupling constant a new divergence may appear in a two-particle spectral function or an existing one may be removed. ...
