Signatures of rare-earth elements in mineralogical form using laser-ablation dual-comb spectroscopy
Christina Hofer, Errol Bowman, Andrew Jarymowycz +9
Spectroscopy of laser-produced plasmas offers an avenue for real-time, standoff and non-preparatory sensing of rare-earth elements (REEs) within a mineralogical context with applic…
Isolating Exciton Dissociation Pathways in ReSe
Bradley G. Guislain, Rysa Greenwood, Matteo Michiardi +13
Strongly bound excitons dominate the optical response in many van der Waals semiconductors, yet distinguishing between the different microscopic processes governing exciton dissoci…
Addressing modulational instability in anti-resonant hollow-core fibers for pulse compression
Michael Hemsworth, TJ Hammond, Arthur K. Mills +1
When pulses propagate in gas-filled anti-resonant hollow-core fibers (AR-HCFs) modulational instability (MI) can lead to pulse break-up and loss of coherence. In pulse broadening a…
Quenching of excitons at grain boundaries in C60 thin films
Rysa Greenwood, Bradley G. Guislain, MengXing Na +12
Exciton lifetimes play a critical role in the performance of organic optoelectronic devices. In this work, we investigate how the presence of multiple rotational domains, and there…
