Research progress on ultrafast electron dynamics in solids
Abstract
<p indent="0mm">The microstructure of matter and the ultrafast processes of electrons fundamentally determine its physical properties and potential applications. Therefore, the study of the ultrafast dynamics of electrons is crucial to reveal the physical properties and changes of matter. Attosecond technology with exceptional temporal resolution provides a new tool for the study of ultrafast electron dynamics in atoms, molecules, and solids. This article focuses on the important area of attosecond science: the ultrafast electron dynamics in solids, offering an overview of research progress of ultrafast dynamic processes of electronic excitation, electron injection, and electron screening in solids based on attosecond transient spectroscopy and time-dependent density functional theory. Furthermore, it provides a prospective on the future development of ultrafast electron dynamics.</p>
