Conducting interface in oxide homojunction: understanding of superior properties in black TiO2
Xujie Lu, Aiping Chen, Yongkang Luo +12
Black TiO2 nanoparticles with a crystalline-core and amorphous-shell structure exhibit superior optoelectronic properties in comparison with pristine TiO2. The fundamental mechanis…
Temperature-tunable Fano resonance induced by strong coupling between Weyl fermions and phonons in TaAs
B. Xu, Y. M. Dai, L. X. Zhao +12
Strong coupling between discrete phonon and continuous electron-hole pair excitations can give rise to a pronounced asymmetry in the phonon line shape, known as the Fano resonance.…
Directly probing spin dynamics in insulating antiferromagnets using ultrashort terahertz pulses
P. Bowlan, S. A. Trugman, X. Wang +6
We investigate spin dynamics in the antiferromagnetic (AFM) multiferroic TbMnO3 using optical- pump, terahertz (THz)-probe spectroscopy. Photoexcitation results in a broadband THz…
Heavy fermion behavior in the quasi-one-dimensional Kondo lattice CeCo2Ga8
Le Wang, Zhaoming Fu, Jianping Sun +13
Dimensionality plays an essential role in determining the anomalous non-Fermi liquid properties in heavy fermion systems. So far most heavy fermion compounds are quasi-two-dimensio…
Optical study of the antiferromagnetic ordered state in electron-overdoped Ca0.77Nd0.23FeAs2
Run Yang, Bing Xu, Yaomin Dai +4
In Ca1-xRExFeAs2 (RE= rare earth), an antiferromagnetic (AFM) phase as well as a structural transition has been reported, even in the electron-overdoped regime. Here we investigate…
Phonon anomalies in some iron-telluride materials
C. C. Homes, Y. M. Dai, J. Schneeloch +2
The detailed temperature dependence of the infrared-active mode in FeTe ( K) and FeTe ( K) has been examined, and the position, width,…
