Atomic Alignment in PbS Nanocrystal Superlattices with Compact Inorganic Ligands via Reversible Oriented Attachment of Nanocrystals
Ahhyun Jeong, Aditya N. Singh, Josh Portner +12
Nanocrystals (NCs) serve as versatile building blocks for the creation of functional materials, with NC self-assembly offering opportunities to enable novel material properties. He…
Trion Formation Hampers Single Quantum Dot Performance in Silane-Coated FAPbBr3 Quantum Dots
Jessica Kline, Shaoni Kar, Benjamin F. Hammel +8
We explore silane-coated formamidinium lead bromide (FAPbBr3) quantum dots as single photon emitters and compare them to FAPbBr3 quantum dots passivated with a phosphoethylammonium…
Emissive Surface Traps Lead to Asymmetric Photoluminescence Line Shape in Spheroidal CsPbBr3 Quantum Dots
Jessica Kline, Shaun Gallagher, Benjamin F. Hammel +9
The morphology of quantum dots plays an important role in governing their photophysics. Here, we explore the photoluminescence of spheroidal CsPbBr3 quantum dots synthesized via th…
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…
Non-Destructive, High-Resolution, Chemically Specific, 3D Nanostructure Characterization using Phase-Sensitive EUV Imaging Reflectometry
Michael Tanksalvala, Christina L. Porter, Yuka Esashi +22
Next-generation nano and quantum devices have increasingly complex 3D structure. As the dimensions of these devices shrink to the nanoscale, their performance is often governed by…
Direct observation of enhanced electron-phonon coupling in copper nanoparticles in the warm-dense matter regime
Quynh L. D. Nguyen, Jacopo Simoni, Kevin M. Dorney +12
Warm-dense matter (WDM) is a highly-excited state that lies at the confluence of solids, plasmas, and liquids and that cannot be described by equilibrium theories. The transient na…
Direct observation of 3D topological spin textures and their interactions using soft x-ray vector ptychography
Arjun Rana, Chen-Ting Liao, Ezio Iacocca +21
Magnetic topological defects are energetically stable spin configurations characterized by symmetry breaking. Vortices and skyrmions are two well-known examples of 2D spin textures…
Origins of size effects in initially dislocation-free single-crystal metallic micro- and nanocubes
Claire Griesbach, Seog-Jin Jeon, David Funes Rojas +6
We report phenomenal yield strengths, up to one fourth of the theoretical strength of silver, recorded in microcompression testing of initially dislocation free silver micro and na…
Singular charge fluctuations at a magnetic quantum critical point
L. Prochaska, X. Li, D. C. MacFarland +12
Strange metal behavior is ubiquitous to correlated materials ranging from cuprate superconductors to bilayer graphene. There is increasing recognition that it arises from physics b…
Creation of high mobility two-dimensional electron gases via strain induced polarization at an otherwise nonpolar complex oxide interface
Yunzhong Chen, Felix Trier, Takeshi Kasama +10
The discovery of two-dimensional electron gases (2DEGs) in SrTiO3-based heterostructures provides new opportunities for nanoelectronics. Herein, we create a new type of oxide 2DEG…
Measurement of the Penetration Depth and Coherence Length of MgB in All Directions Using Transmission Electron Microscopy
J. C. Loudon, S. Yazdi, T. Kasama +2
We demonstrate that images of flux vortices in a superconductor taken with a transmission electron microscope can be used to measure the penetration depth and coherence length in a…
Room temperature formation of high-mobility two-dimensional electron gases at crystalline complex oxide interfaces
Y. Z. Chen, N. Bovet, T. Kasama +5
Well-controlled sub-unit-cell layer-by-layer epitaxial growth of spinel alumina is achieved at room temperature on the TiO2-terminated SrTiO3 single crystalline substrate. By tailo…
