Field-Induced Dissociation Reveals Excitonic Long-Range Photocarrier Transport in Bulk-Insulating Bi2Se3 Nanoribbons
Rodrigo Becerra Silva, Xiang Yi, Ziyi Song +1
Photoexcited charge carriers in topological insulators display anomalously long-range transport at cryogenic temperatures, but the underlying mechanism remains under debate. Here w…
Super-diffusion of Photoexcited Carriers in Topological Insulator Nanoribbons
Rodrigo Becerra Silva, Jay Huang, Bob Minyu Wang +3
Understanding the ultrafast dynamics and transport of photoexcited carriers in topological insulators is crucial for the optical manipulation of spins and may shed light on the nat…
Electrically Switchable Circular Photogalvanic Effect in Methylammonium Lead Iodide Microcrystals
Yuqing Zhu, Ziyi Song, Rodrigo Becerra Silva +6
We investigate the circular photogalvanic effect (CPGE) in single-crystalline methylammonium lead iodide microcrystals under a static electric field. The external electric field ca…
Surface Effects on Anisotropic Photoluminescence in One-Dimensional Organic Metal Halide Hybrids
Luke M. McClintock, Long Yuan, Ziyi Song +10
One-dimensional (1D) organic metal halide hybrids exhibit strongly anisotropic optical properties, highly efficient light emission, and large Stokes shift, holding promises for nov…
