Progress on terahertz time-domain spectrum technology in the field of materials science
Terahertz time-domain spectroscopy is a powerful tool to study the ultrafast dynamics of charge carriers and the photoconductivity of materials.Recently,with the rapid development of materials science,terahertz time-domain spectroscopy technology has been widely used to study the ultrafast dynamics of particles and quasi-particles such as photo excited charge carriers,exciton and polaron in functional materials including two-dimensional layered materials,organic-inorganic perovskite materials,and low-dimensional carbon materials.In this view,we focus on the recent research progress of terahertz time-domain spectroscopy technology in the field of materials science in the past 5 years,and outlook on the potential application of terahertz time-domain spectroscopy technology in the field of materials science.
