Trion induced negative photoconductivity in monolayer MoS2
C. H. Lui, A. J. Frenzel, D. V. Pilon +5
Optical excitation typically enhances electrical conduction and low-frequency radiation absorption in semiconductors. We have, however, observed a pronounced transient decrease of…
Observation of a warped helical spin-texture in BiSe from circular dichroism angle-resolved photoemission spectroscopy
Y. H. Wang, D. Hsieh, D. Pilon +4
A differential coupling of topological surface states to left- versus right-circularly polarized light is the basis of many opto-spintronics applications of topological insulators.…
Comparison of Birefringent Metamaterials and Meanderline Structure as Quarter-Wave Plates at Terahertz Frequencies
Andrew C. Strikwerda, Kebin Fan, Hu Tao +3
We have fabricated a quarter-wave plate from a single layer birefringent metamaterial. For comparison, an appropriately scaled double layer meanderline structure was fabricated. At…
Highly-flexible wide angle of incidence terahertz metamaterial absorber
Hu Tao, C. M. Bingham, A. C. Strikwerda +7
We present the design, fabrication, and characterization of a metamaterial absorber which is resonant at terahertz frequencies. We experimentally demonstrate an absorptivity of 0.9…
