Light-Driven Nanoscale Vectorial Currents
Jacob Pettine, Prashant Padmanabhan, Teng Shi +16
Controlled charge flows are fundamental to many areas of science and technology, serving as carriers of energy and information, as probes of material properties and dynamics, and a…
Tracking ultrafast photocurrents in the Weyl semimetal TaAs using THz emission spectroscopy
N. Sirica, R. I. Tobey, L. X. Zhao +14
We investigate polarization-dependent ultrafast photocurrents in the Weyl semimetal TaAs using terahertz (THz) emission spectroscopy. Our results reveal that highly directional, tr…
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…
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…
