Bulk photovoltaic effect in two-dimensional ferroelectric semiconductor -InSe
Xiaojuan Chen, Kang Xu, Tingxiao Qin +4
Bulk photovoltaic effect, which arises from crystal symmetry-driven charge carrier separation, is an intriguing physical phenomenon that has attracted extensive interest in photovo…
Coupling of optical phonons with Kondo effect and magnetic orders in antiferromagnetic Kondo lattice CeAuSb
Yin-Zou Zhao, Qi-Yi Wu, Chen Zhang +14
Ultrafast optical spectroscopy was used to investigate the ultrafast quasiparticle dynamics of antiferromagnetic Kondo lattice CeAuSb as a function of temperature and fluence.…
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-…
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…
A dynamical stability limit for the charge density wave in K0.3MoO3
Roman Mankowsky, Biaolong Liu, Srivats Rajasekaran +6
We study the response of the one-dimensional charge density wave in K0.3MoO3 to different types of excitation with femtosecond optical pulses. We compare the response to direct exc…
Unusual Fermi Surface Sheet-Dependent Band Splitting in Sr2RuO4 Revealed by High Resolution Angle-Resolved Photoemission
Shanyu Liu, Hongming Weng, Daixiang Mou +17
High resolution angle-resolved photoemission measurements have been carried out on Sr2RuO4. We observe clearly two sets of Fermi surface sheets near the (π,0)-(0,π) line which are…
