Title: Local characterization of a heavy-fermion superconductor via sub-Kelvin magnetic force microscopy

Abstract

Using magnetic force microscopy operating at sub-Kelvin temperatures, we characterize the heavy fermion superconductor CeCoIn5. We pinpoint the absolute London penetration depth of λ(0)=435 ± 20 nm and report its temperature dependence, which is closely linked to the symmetry of the superconducting gap. In addition, we directly measure the pinning force of individual Abrikosov vortices and estimate the critical current density of jc=9×104 A/cm2. In contrast to the related, well-established tunnel diode oscillator technique, our method is capable of resolving inhomogeneities locally on the micrometer scale at ultra-low temperature.

Scattering evidence of positional charge correlations in polyelectrolyte complexes

Journal Article Fang, Yan N. ; Rumyantsev, Artem M. ; Neitzel, Angelika E. ; ... - Proceedings of the National Academy of Sciences of the United States of America

Polyelectrolyte complexation plays an important role in materials science and biology. The internal structure of the resultant polyelectrolyte complex (PEC) phase dictates properties such as physical state, response to external stimuli, and dynamics. Small-angle scattering experiments with X-rays and neutrons have revealed structural similarities between PECs and semidilute solutions of neutral polymers, where the total scattering function exhibits an Ornstein–Zernike form. In spite of consensus among different theoretical predictions, the existence of positional correlations between polyanion and polycation charges has not been confirmed experimentally. Here, we present small-angle neutron scattering profiles where the polycation scattering length density is matched tomore »« less

Polarity compensation mechanisms on the perovskite surface KTaO ₃ (001)

Journal Article Setvin, Martin ; Reticcioli, Michele ; Poelzleitner, Flora ; ... - Science

The stacking of alternating charged planes in ionic crystals creates a diverging electrostatic energy—a “polar catastrophe”—that must be compensated at the surface. We used scanning probe microscopies and density functional theory to study compensation mechanisms at the perovskite potassium tantalate (KTaO₃) (001) surface as increasing degrees of freedom were enabled. The as-cleaved surface in vacuum is frozen in place but immediately responds with an insulator-to-metal transition and possibly ferroelectric lattice distortions. Annealing in vacuum allows the formation of isolated oxygen vacancies, followed by a complete rearrangement of the top layers into an ordered pattern of KO and TaO₂ stripes. Themore »« less

Direct functionalization of C−H bonds by electrophilic anions

Journal Article Warneke, Jonas ; Mayer, Martin ; Rohdenburg, Markus ; ... - Proceedings of the National Academy of Sciences of the United States of America

Significance Functionalization of unreactive molecules is a significant chemical challenge relevant to the conversion of abundant feedstocks such as alkanes into high-value chemicals. Herein, we demonstrate a new mechanism of alkane functionalization by the substitution of a proton by an anion in an alkyl chain. The reactive anion used for this reaction is generated from a highly stable precursor. The reaction mechanism is established using experimental and computational approaches, and the products are collected in the condensed phase using high-flux mass-selected ion deposition. This paves the way for exploiting the properties of gaseous ions for the generation of complex molecularmore » structures in the condensed phase.« less

Enhanced FIB-SEM systems for large-volume 3D imaging

Journal Article Xu, C. Shan ; Hayworth, Kenneth J. ; Lu, Zhiyuan ; ... - eLife

Focused Ion Beam Scanning Electron Microscopy (FIB-SEM) can automatically generate 3D images with superior z-axis resolution, yielding data that needs minimal image registration and related post-processing. Obstacles blocking wider adoption of FIB-SEM include slow imaging speed and lack of long-term system stability, which caps the maximum possible acquisition volume. Here, we present techniques that accelerate image acquisition while greatly improving FIB-SEM reliability, allowing the system to operate for months and generating continuously imaged volumes > 10 ⁶ ?m ³ . These volumes are large enough for connectomics, where the excellent z resolution can help in tracing of small neuronal processesmore »« less

Electrically switchable metallic polymer metasurface device with gel polymer electrolyte

Journal Article de Jong, Derek ; Karst, Julian ; Ludescher, Dominik ; ... - Nanophotonics

Abstract We present an electrically switchable, compact metasurface device based on the metallic polymer PEDOT:PSS in combination with a gel polymer electrolyte. Applying square-wave voltages, we can reversibly switch the PEDOT:PSS from dielectric to metallic. Using this concept, we demonstrate a compact, standalone, and CMOS compatible metadevice. It allows for electrically controlled ON and OFF switching of plasmonic resonances in the 2–3 µm wavelength range, as well as electrically controlled beam switching at angles up to 10°. Furthermore, switching frequencies of up to 10 Hz, with oxidation times as fast as 42 ms and reduction times of 57 ms, are demonstrated. Our workmore »« less
