pH Regulates Ion Dynamics in Carboxylated Mixed Conductors
Zeyuan Sun, Mengting Sun, Rajiv Giridharagopal +12
Coupled ionic and electronic transport underpins processes as diverse as electrochemical energy conversion, biological signaling, and soft adaptive electronics. Yet, how chemical e…
Free Space Few-Photon Nonlinearity in Critically Coupled Polaritonic Metasurfaces
Jie Fang, Abhinav Kala, Rose Johnson +15
Few-photon optical nonlinearity in planar solid-state systems is challenging yet crucial for quantum and classical optical information processing. Polaritonic nonlinear metasurface…
Multi-Output Convolutional Neural Network for Improved Parameter Extraction in Time-Resolved Electrostatic Force Microscopy Data
Madeleine D. Breshears, Rajiv Giridharagopal, David S. Ginger
Time-resolved scanning probe microscopy methods, like time-resolved electrostatic force microscopy (trEFM), enable imaging of dynamic processes ranging from ion motion in batteries…
Sub-diffraction Imaging of Carrier Dynamics in Halide Perovskite Semiconductors: Effects of Passivation, Morphology, and Ion Motion
Madeleine D. Breshears, Justin Pothoof, Rajiv Giridharagopal +1
We spatially resolve photocarrier dynamics in halide perovskites using time-resolved electrostatic force microscopy (trEFM) to map surface potential equilibration during photoexcit…
Ligand Equilibrium Influences Photoluminescence Blinking in CsPbBr3: A Change Point Analysis of Widefield Imaging Data
Shaun Gallagher, Jessica Kline, Farzaneh Jahanbakhshi +5
Photoluminescence intermittency remains one of the biggest challenges to realizing perovskite quantum dots (QDs) as scalable single photon emitters. We compare CsPbBr3 QDs capped w…
Optical tuning of the diamond Fermi level measured by correlated scanning probe microscopy and quantum defect spectroscopy
Christian Pederson, Rajiv Giridharagopal, Fang Zhao +4
Quantum technologies based on quantum point defects in crystals require control over the defect charge state. Here we tune the charge state of shallow nitrogen-vacancy and silicon-…
