Abstract
Exploiting of unique quantum states in topological insulators is expected to realize new applications of THz technology. Among various kinds of topological materials, GeTe/Sb 2 Te 3 , that is multilayered system consist of topological insulator and normal insulator, has been received remarkable attention. In this study, we investigated THz transmission and emission property in interfacial phase change memory material [(GeTe) 2 /(Sb 2 Te 3 )1]n and Ge 2 Sb 2 Te 5 alloy. In addition, to understand the basic property of material, we also used GeTe and Sb 2 Te 3 . We observed pronounced differences between multilayered system and alloy.
