Defect Engineering in Plasmonic Metal Oxide Nanocrystals
(Journal article; Peer reviewed, 2016)Defects may tend to make crystals interesting but they do not always improve performance. In doped metal oxide nanocrystals with localized surface plasmon resonance (LSPR), aliovalent dopants and oxygen vacancies act as ... -
Observation of uncompensated bound charges at improper ferroelectric domain walls
(Journal article; Peer reviewed, 2019)Low-temperature electrostatic force microscopy (EFM) is used to probe unconventional domain walls in the improper ferroelectric semiconductor Er0.99Ca0.01MnO3 down to cryogenic temperatures. The low-temperature EFM maps ... -
Propagation Length of Antiferromagnetic Magnons Governed by Domain Configurations
(Peer reviewed; Journal article, 2019)The compensated magnetic order and characteristic terahertz frequencies of antiferromagnetic materials make them promising candidates to develop a new class of robust, ultrafast spintronic devices. The manipulation of ... -
Proximity-Induced Superconductivity in CdTe-HgTe Core-Shell Nanowires
(Journal article; Peer reviewed, 2019)In this Letter we report on proximity superconductivity induced in CdTe–HgTe core–shell nanowires, a quasi-one-dimensional heterostructure of the topological insulator HgTe. We demonstrate a Josephson supercurrent in our ... -
Single-Mode Near-Infrared Lasing in a GaAsSb-Based Nanowire Superlattice at Room Temperature
(Journal article; Peer reviewed, 2018)Semiconductor nanowire lasers can produce guided coherent light emission with miniaturized geometry, bringing about new possibilities for a variety of applications including nanophotonic circuits, optical sensing, and ... -
Solvent-Controlled Charge Storage Mechanisms of Spinel Oxide Electrodes in Mg Organohaloaluminate Electrolytes
(Journal article; Peer reviewed, 2017)Considering the improved safety, reduced cost, and high volumetric energy density associated with Mg batteries, this technology has distinct advantages for large-scale energy storage compared to other existing battery ... -
Topological defects in hexagonal manganites - Inner structure and emergent electrostatics
(Journal article; Peer reviewed, 2017)Diverse topological defects arise in hexagonal manganites, such as ferroelectric vortices, as well as neutral and charged domain walls. The topological defects are intriguing because their low symmetry enables unusual ...
