Realization of a photonic topological insulator in Kagome crystals at terahertz wavelengths
Yun Shen, Jie Ji, Le Zhang +8
Topological systems are inherently robust to disorder and continuous perturbations, resulting in dissipation-free edge transport of electrons in quantum solids, or reflectionless g…
Manipulating organic semiconductor morphology with visible light
Michael Korning Sorensen, Anders Skovbo Gertsen, Rocco Peter Fornari +11
We present a method to manipulate the final morphology of roll-to-roll slot-die coated poly(3-hexylthiophene) (P3HT) by optically exciting the p-type polymer in solution while coat…
Fermi velocity renormalization in graphene probed by terahertz time-domain spectroscopy
Patrick R. Whelan, Qian Shen, Binbin Zhou +13
We demonstrate terahertz time-domain spectroscopy (THz-TDS) to be an accurate, rapid and scalable method to probe the interaction-induced Fermi velocity renormalization νF^* of cha…
Mono-crystalline Gold Platelets: A High Quality Platform for Surface Plasmon Polaritons
Korbinian J. Kaltenecker, Enno Krauss, Laura Casses +5
We use mono-crystalline gold platelets with ultra-smooth surfaces and superior plasmonic properties to investigate the formation of interference patterns caused by surface plasmon…
Terahertz emission from laser-driven gas-plasmas: a plasmonic point of view
I. Thiele, B. Zhou, A. Nguyen +8
We disclose an unanticipated link between plasmonics and nonlinear frequency down-conversion in laser-induced gas-plasmas. For two-color femtosecond pump pulses, a plasmonic resona…
Picosecond Dynamics of Internal Exciton Transitions in CdSe Nanorods
David G. Cooke, Peter Uhd Jepsen, Jun Yan Lek +3
The picosecond dynamics of excitons in colloidal CdSe nanorods are directly measured via their 1s to 2p-like internal transitions by ultra-broadband terahertz spectroscopy. Broaden…
