Relaxation dynamics of the optically driven nonequilibrium states in the electron- and hole-doped topological-insulator materials $(B{i}_{1-x}S{b}_x{)}_{2}T{e}_3$

Chris Reinhoffer, Yu Mukai, Semyon Germanskiy +7

We report on time-resolved mid-infrared-pump terahertz-transmission-probe studies of the topological-insulator materials $(B{i}_{1-x}S{b}_x{)}_{2}T{e}_3$, in which by varying x charge…
