Chiral charge-density wave in TiSe due to photo-induced structural distortions
Darshana Wickramaratne, Richard Schaller, Gary Wiederrecht +2
A variety of experiments have been carried out to establish the origin of the chiral charge-density wave transition in 1T-TiSe, which in turn has led to contradictory conclusio…
Momentum-resolved surface enhanced Raman scattering from a nanowire-nanoparticle junction cavity
Adarsh B. Vasista, Shailendra K. Chaubey, David J. Gosztola +3
Herein we report experimental evidence of directional SERS from molecules situated inside a single nanowire-nanoparticle junction cavity. The emission was confined to a narrow rang…
Ultrafast dynamics in normal and Charge Density Wave phase of 2H-NbSe2
A. Anikin, R. D. Schaller, G. P. Wiederrecht +3
We investigate carrier and collective mode dynamics in 2H-NbSe using time-resolved optical pump-probe spectroscopy and compare the results with first-principle calculations. Br…
Accelerating ultrafast spectroscopy with compressive sensing
Sushovit Adhikari, Cristian L. Cortes, Xiewen Wen +5
Ultrafast spectroscopy is an important tool for studying photoinduced dynamical processes in atoms, molecules, and nanostructures. Typically, the time to perform these experiments…
Phonon-pump electronic-probe study of methylammonium lead iodide reveals electronically decoupled organic and inorganic sublattices
Peijun Guo, Arun Mannodi-Kanakkithodi, Jue Gong +10
Organic-inorganic hybrid perovskites such as methylammonium lead iodide (CH3NH3PbI3) are game-changing semiconductors for solar cells and light-emitting devices owing to their exce…
Photon-Induced Selenium Vacancies in TiSe2
David B. Lioi, David J. Gosztola, Gary P. Wiederrecht +1
TiSe2 is a member of transition metal dichalcogenide family of layered van-der-Waals materials that exhibits some distinctive electronic and optical properties. Here, we perform Ra…
