Photon bunching in cathodoluminescence induced by indirect electron excitation
Vasudevan Iyer, Kevin Roccapriore, Jacob Ng +3
The impulsive excitation of ensembles of excitons or color centers by a high-energy electron beam results in the observation of photon bunching in the second-order correlation func…
Mapping the Pathways of Photo-induced Ion Migration in Organic-inorganic Hybrid Halide Perovskites
Taeyong Kim, Soyeon Park, Vasudevan Iyer +7
Organic-inorganic hybrid perovskites (OIHPs) exhibiting exceptional photovoltaic and optoelectronic properties are of fundamental and practical interest, owing to their tunability…
Correlative nanoscale imaging of strained hBN spin defects
David Curie, Jaron T. Krogel, Lukas Cavar +11
Spin defects like the negatively charged boron vacancy color center () in hexagonal boron nitride (hBN) may enable new forms of quantum sensing with near-surface defects in…
Hyperspectral nanoscale mapping of hybrid perovskite photophysics at the single grain level
Ethan J. Taylor, Vasudevan Iyer, Bibek S. Dhami +3
Hybrid organic-inorganic perovskites have drawn significant interest for applications in optoelectronics over the last few years. Despite rapid progress in understanding the photop…
Angle-Resolved Cathodoluminescence Polarimetry of Hybrid Perovskites
Bibek S. Dhami, Vasudevan Iyer, Aniket Pant +3
Coupling between light and matter strongly depends on the polarization of the electromagnetic field and the nature of the excitations in the material. As hybrid perovskites emerge…
Near-field imaging of plasmonic nanopatch antennas with integrated semiconductor quantum dots
Vasudevan Iyer, Yoong Sheng Phang, Andrew Butler +5
Plasmonic nanopatch antennas that incorporate dielectric gaps hundreds of picometers to several nanometers thick have drawn increasing attention over the past decade because they c…
Mid-Infrared Ultrafast Carrier Dynamics in Thin Film Black Phosphorus
Vasudevan Iyer, Peide Ye, Xianfan Xu
