Ultrafast Carrier Dynamics Study of Bismuth tellurium
碩士 === 國立中山大學 === 光電工程學系研究所 === 106 === In this thesis, temperature-dependent(78K~290K) coherent phonon dynamics in topological insulator Bi2Te3 are investigated by ultrafast pump-probe system. Four coherent phonon types(A1g1、A1g2、Eg2、coherent acoustic phonon) with strong temperature dependency are...
