固体的阿秒光谱学：晶格散射引起的条纹相移
Attosecond spectroscopy of solids: streaking phase shift due to lattice scattering
摘要：
本文发展了一个完全考虑能带结构效应的固体激光辅助光电子发射理论。带隙附近的强晶格散射导致条纹谱图的100 As量级的失真和时间移位。用Bloch电子动力学解释了这种效应，并表明对于任意小的光电子平均自由程，这种效应仍然很大。L. Cavalieri等人，Nature（London）{ \bf 449}，1029（2007）]
英文摘要：
Theory of laser-assisted photoemission from solids is developed for a numerically exactly solvable model with full inclusion of band structure effects. The strong lattice scattering in the vicinity of band gaps leads to a distortion and a temporal shift of the streaking spectrogram of the order of 100 as. The effect is explained in terms of Bloch electron dynamics and is shown to remain large for an arbitrarily small photoelectron mean free path. The implications for the streaking experiment on W(110) [A. L. Cavalieri et al., Nature (London) {\bf 449}, 1029 (2007)]
