The optoelectronic performance of lead halide perovskite in highfluence applications are hindered by heterogeneous multi-polaron interactions in the nanoscale. Here, Nishda et al. spatially resolve sub-ns relaxation dynamics on the nanometer scale by

Ultrafast infrared nano-imaging has enabled the study of nanoscale dynamics, but has been limited to probing short-lived carrier lifetimes. Here, the authors present pump-probe nano-spectroscopy with enhanced sensitivity to image both carrier and vib

As variable renewable energy generation in Texas increases over the next decade, flexibility and system inertia needs are likely to increase. Although natural gas peakers and combined cycle plants have met these demands in the past, grid-scale energy

We perform ultrafast pump-probe nano-spectroscopic imaging of WSe2-SiO2 interfaces. From transient phonon softening as a local probe of substrate temperature, we resolve heterogeneity in ps thermalization and quantify interfacial boundary conductance

Nanoscale infrared (IR) resonators with sub-diffraction limited mode volumes and open geometries have emerged as new platforms for implementing cavity quantum electrodynamics (QED) at room temperature. The use of infrared (IR) nano-antennas and tip n

Ultrafast infrared nano-imaging has demonstrated access to ultrafast carrier dynamics on the nanoscale in semiconductor, correlated-electron, or polaritonic materials. However, mostly limited to short-lived transient states, the contrast obtained has
