Description:
Author(s): Young Gwan Choi, Chan June Zhung, Sun-Hee Park, Joonbum Park, Jun Sung Kim, Seongheun Kim, Jaehun Park, and J. S. Lee Using optical-pump terahertz-probe spectroscopy, we investigated an ultrafast photocarrier relaxation behavior in a B i 1.5 S b 0.5 T e 1.7 S e 1.3 (BSTS) single crystal, which is one of the most bulk-insulating topological insulators. Compared to n -type bulk-metallic B i 2 S e 3 , we found that BSTS endows distinct... [Phys. Rev. B 97, 075307] Published Fri Feb 23, 2018
