Ultrafast charge-transfer dynamics in CaCuOCl from time-resolved optical reflectivity
Haiyun Huang, Xiu Zhang, Junzhi Zhu +7
We employ time-resolved optical reflectivity to investigate the ultrafast dynamics of the charge-transfer gap (CTG) in a parent cuprate compound CaCuOCl (CCOC). We obse…
Ultrafast hot carrier dynamics of ZrTe from time-resolved optical reflectivity
Xiu Zhang, Hai-Ying Song, X. C. Nie +8
We investigate the hot carrier dynamics of ZrTe by ultrafast time-resolved optical reflectivity. Our results reveal a phonon-mediated across-gap recombination, consistent with…
Photoinduced two-step insulator-metal transition in Ti4O7 by ultrafast time-resolved optical reflectivity
X. C. Nie, Hai-Ying Song, Xiu Zhang +6
We report on systematic investigation of hot carrier dynamics in Ti4O7 by ultrafast time-resolved optical reflectivity. We find the transient indication for its two-step insulator-…
Study of pseudogap and superconducting quasiparticle dynamics in by time-resolved optical reflectivity
X. C. Nie, Hai-Ying Song, Xiu Zhang +8
The relation between pseudogap (PG) and superconducting (SC) gap, whether PG is a precursor of SC or they coexist or compete, is a long-standing controversy in cuprate high-tempera…
Transient transition from free carrier metallic state to exciton insulating state in GaAs by ultrafast photoexcitation
X. C. Nie, H. Y. Liu, Xiu Zhang +6
We present systematic studies of the transient dynamics of GaAs by ultrafast time-resolved optical reflectivity. In photo excited non-equilibrium states, we found a sign reverse in…
