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…
Probing and controlling terahertz-driven structural dynamics with surface sensitivity
P. Bowlan, J. Bowlan, S. A. Trugman +8
Intense, single-cycle terahertz (THz) pulses offer a promising approach for understanding and controlling the properties of a material on an ultrafast time scale. In particular, re…
Ultrafast Polaron Dynamics in Layered and Perovskite Manganites: 2D and 3D Polarons
J. Lee, H. J. Lee, R. D. Averitt +8
We have studied the sub-picosecond quasiparticle dynamics in the perovskite manganite La0.7Ca0.3MnO3 and the layered manganite La1.4Sr1.6Mn2O7 using ultrafast optical spectroscopy.…
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…
Using ultrashort optical pulses to couple ferroelectric and ferromagnetic order in an oxide heterostructure
Y. M. Sheu, S. A. Trugman, L. Yan +3
A new approach to all-optical detection and control of the coupling between electric and magnetic order on ultrafast timescales is achieved using time-resolved second harmonic gene…
Time-resolved terahertz dynamics in thin films of the topological insulator BiSe
R. Valdés Aguilar, J. Qi, M. Brahlek +7
We use optical pump--THz probe spectroscopy at low temperatures to study the hot carrier response in thin BiSe films of several thicknesses, allowing us to separate the bul…
