Terahertz (THz) technology has attracted great attention for its application potential in next-generation communications, medical imaging, security, etc. The investigation on the interaction of THz wave and functional materials is the fundamental issues for exploring new physics in condensed matter and then developing advanced THz devices. This review elucidates some emergent work focusing on this point, including ultrafast phenomena studied using time-resolved THz spectroscopy, nanoparticles as contrast agents for THz medical imaging, and spintronics in THz range. The technical problems and research difficulties for present and future work are also presented. This review aims to afford researchers a better understanding of the different THz function materials and their applications.
