Abstract: This study comprehensively investigated the coherent lattice dynamics in Bi2Se3 by ultrafast optical pump-probe spectroscopy with tunable near-infrared probe pulses. Sample-thickness- and probe-wavelength-dependent experiments revealed the key role of Bi2Se3 optical property in the generation… read more here.
